What is Palladium?

Sunday, August 30th, 2009

We see the word palladium on jewelry store signs, on websites that offer for you to sell your jewelry, and we hear it on TV and the radio. It must have something to do with precious metals, but what is it?

Palladium is in the same family of metals as platinum, called (appropriately) platinum group metals (or PGMs). Rhodium, ruthenium, iridium, osmium, and platinum are the other PGMs. While palladium is the least dense metal in the group, it shares certain properties with its sister metals. Palladium also has the lowest melting point.

Palladium was discovered in 1803 as crude palladium ore. It was discovered by William Hyde Wollaston, who peformed chemcial processes to extract the palladium metal from the ore. He named it Palladium after 2 Pallas, an asteroid that was discovered a few years prior. In Greek mythology, Pallas was killed by Athena. Athena felt so guilty that she created a “palladium,” a wooden image of Pallas and took on Pallas’ name.

Wollaston was a brilliant chemist who did important work in optical theory and electricity. He also invented the process of extracting palladium to extract the metal – it involved dissolving the ore, neutralizing the solution, and then adding certain chemicals to produce the desired effect.

What resulted was palladium, a silvery-white metal that is lustrous. It is rare, but very useful. It’s main use is in automobiles – it is a key component of a catalytic converter. This makes palladium a very useful “green substance”, in a way, because the catalytic converter of a car is what converts the harmful gas emissions of cars into less harmful gases.

Palladium is also used in manufacturing SED/OLED/LCD television sets, in cold fusion technology, and even in dentistry. None of those are the reasons we’ve been seeing this word lately. Palladium has been used to make jewelry since 1939. For a long time palladium was mainly used as an alloy to help make white gold – it has a natural whitish color that makes it so that rhodium plating isn’t necessary. Since 2004, when gold and platinum prices were extra high, jewelers (especially in China) have been making palladium jewelry.

Palladium leaf is used for the illumination of manuscripts. Silver leaf does not have staying power because it tarnishes so quickly. Aluminum isn’t great either, because it’s really hard to work with and does not produce the same type of result. Palladium leaf is preferred second to gold leaf in the illumination of manuscripts.

Companies are now buying used palladium, and that is both helpful to keep down mining, which is extremely environmentally destructive. That truly does make the palladium in a catalytic converter a “green” occurrence, as the recovered and recycled palladium can be reused in the increasingly more efficient production of catalytic converters.

As for palladium jewelry, it has the look of platinum at less cost, making it a smart choice for tough economic times.

Recycling Household Items

Sunday, August 30th, 2009

We are constantly being told to recycle as much of our waste as we can. Tin cans and cardboard boxes are easy enough to recycle as there are usually recycling stations dotted around town and some counties even pick your recycling up for you. Larger items are another issue however, and we don’t really get told what to do with these. Units such as wardrobes and draws and other things like seating and doors too often end up being thrown on the tip and wasted for good. In these difficult times we should be looking to make use of as much waste as we can, so here are a few tips to household recycling.


Wood. People often throw out things like dining furniture, wardrobes and cupboards without really considering what they could be used for. You would be amazed how quickly you can make a quirky coffee table by screwing a couple of kitchen units together and taking the knobs off the doors. The best bit is that the coffee table will double up as storage space as you can just open the lid and pop stuff in. You can also use wood to make lots of little things such as door stops and chopping boards and even wine racks


Glassware. You might think that you need a kiln in order to recycle glass, but you’d be wrong.Glasses can be used to pot house plants, store knick-knacks in, and even create feature walls with if you’ve got the time to make it. If you put a little thought into it first, you need never have to throw another glass away.

Furniture. This is one of the hardest things to recycle and I’m not saying that you will be able to make tableware out of your old sofa, but sometimes there is scope to get a few more years out of items you thought were at the end of their life. The garden is a great place to find a home for old household items.As long as you protect the furniture from the outdoor conditions with good varnish, you can enjoy old tables and chairs in the fresh air for a long time. Also, things like carpet can be cut up and used to kneel on when gardening to save getting your clothes dirty.

One way a lot of people have found to save money is by going with solar energy in their homes.  Usually this is very expensive to do.  But people have been very resourceful and have found many ways to get cheap solar panels for their solar energy system.Usuallly what it would cost to have some electrical company go and install it for you would cost thousands of dollars.But by making the effort to locate inexpensive systems this will save a lot of money also.

Another way they have chosen to go is intstead of buying some solar panels they have chosen to learn how to build a solar panel themselves.It is not as difficult as it seems.  Also there are many instructions out there that can teach them how to do it.  By doing it themselves this again can save them thousands of dollars.

Now everybody may not be the DIY solar panels maker but these guides are so good you could even have someone build it for you.Once more doing this would save a lot of money compared to buying some pre made solar panels. 

Either way you will be saving money and energy in the long run.  So if you go with buying some inexpensive solar panels and installling it yourself that will save you money.Or if you make the choice of building it yourself, you are going to be saving quite a bit of money.  So in a time when you need to save money, this is a good way to go.

Solar Panel: What Kind of Maintenance Do They Need?

Sunday, August 30th, 2009

If you think having solar panels installed on your home will result in expensive, time-consuming maintenance, you can stop worrying.  Residential solar panels are manufactured using thick glass encapsulate the solar cells and are then affixed to a metal framework.   Since the solar panels have no moving parts, they require very little maintenance after being installed.

Interested In Maintenance? Then What About Constructing Your Own Solar Energy?

Now, this may be subject to where you reside, the kind of weather typical for your region and whether or not your yard has a lot of trees.  For instance, if you live in a region where there is a lot of snow in the winter, you may have to spend some time following a heavy snowfall cleaning off the solar panels so the sun can penetrate them.  Or if you reside in an area that experiences frequent dust storms, or in a city where there is a lot of dirt in the air, you may have to clean the glass panels periodically to ensure their efficiency.    But if there is a ample amount of rain, that should keep your solar panels clean enough to function properly.

If there are a lot of deciduous trees on your property, including evergreen trees, you may need to make sure that the leaves or needles don’t cover the solar panels.  A quick sweep of the broom should take care of it.

Discover Ways To Build Your Solar Panels Here

As we know, the solar panels are not the only components in the system.  If yours is an off grid system, it will include storage batteries and maybe a back up generator.   These things will require more monitoring and ongoing care than the solar panels themselves.  It would be wise to schedule regular inspections to make sure that the whole solar energy system is working properly.

If your solar panels are connected to the grid, you will still have an inverter as part of your system.  An inverter takes the electricity generated by your solar panels and converts it to alternating current for your appliances.  Even though it has no mechanical parts, it is an important component and should be regularly inspected.

Here Are The Most Utilised Methods Today
