Silicon is the most abundant element on earth after oxygen.Large amounts of silicon can be found in various minerals and it is abundant in oceans and nearly all other waters as silicic acid. In the surface layers of oceans silicon concentrations are 30 ppb, whereas deeper water layers may contain 2 ppm silicon.

contact usThe hard part is obtaining good quality elemental silicon. The next intricate part is synthesizing and distilling (separating out) the silane intermediates from which silicone molecules are built. That means that a huge mixture of different reaction products has to be purified to the highest degree to allow their further use for all the different high-quality products.
