Silex Chemicals SC UG is a manufacturer and supplier of high purity chlorosilanes.

Our team has more than 20 years experience of producing and selling chlorosilanes. Silex Chemicals SC UG introduces new technologies, and that is why we can now offer a stable supply of high purity products in any quantities required. Hexachlorodisilane (HCDs) is recognized to be a potential precursor for ALD processes. For example, recent research on purification of Hexachlorodisilanes made it possible for us to increase the capacity to 15% and have the best product purity rates than ever before. The level of impurities in our products is just a few parts per billion (ppb). We have in-house analytical capabilities that minimize the time between synthesis and shipping. These include ICP-OES, AA, GC, FTIR and HPLC capabilities. In addition, we use specialized contractual analytical laboratories to carry out ultra-high purity analysis, e.g. ICP-MS for parts per billion (ppb) and parts per trillion (ppt) trace analysis and XRD for conformational analysis. The main products of Silex Chemicals SC UG include precursor chemicals used in high-technology applications, especially in the semiconductor industry. However, we are not limited to high technologies alone. We welcome inquiries regarding any and all synthesis and purification projects.


In a world with a continuously increasing population and limited resources, the idea of a sustainable development of society is of major importance. Only research and innovation will allow for the development of economic and social networks and processes that fulfill the requirements of sustainability. Sustainability in science and technology begins when we start thinking of how to solve a problem or how to turn science into technological applications. Chemistry, as the a science of matter and its transformation, plays a central role in this process.Sustainability is integral in everything we do. From the raw materials we source and the way we use them, to the products we create and the people who produce them, we believe in being a responsible company. Our approach to sustainability evolves as the world around us changes, but it has always been and will remain a central element of the way we do business.
