Tellurium :

Tellurium is a chemical element with symbol Te and atomic number 52. A brittle, mildly toxic, rare, silver-white metalloid which looks similar to tin, tellurium is chemically related to selenium and sulfur. It is occasionally found in native form, as elemental crystals. Tellurium is far more common in the universe as a whole than it is on Earth. Its extreme rarity in the Earth's crust, comparable to that of platinum, is partly due to its high atomic number, but also due to its formation of a volatile hydride which caused the element to be lost to space as a gas during the hot nebular formation of the planet.

Siman Ltd has started its activities in 1994 as a company for trade and distribution of chemical products. For this period we have been able to establish close collaboration and relationship with our customers and suppliers. While constantly trying to determinate and even predict the actual needs of our partners, we have ever been able to expand the list of the products we are supplying and to improve our service. As an end result of this consequent striving for perfectness we have implemented the system for quality management –ISO 9001:2008, which simply serves to one more time prove our commitment to maintain our highly professional level of customer service.

The main activity of Siman Ltd is trading with chemical products, non ferrous metals and fertilizers over the territory of Bulgaria and worldwide. We have well established partnership network in more than 30 countries around the globe. It’s exactly these relationships that make our main capital, capital that we count on.
