SYMULOX M72 is widely used as a high-grade raw material, primarily in the refractory industry. It is an entirely new type of a zircon mullite. One of the major quality characteristics of the new synthetic sintered quality is the combination of low level of impurities and a genuine, homogeneous and microcrystalline structure. It is used as synthetic raw materials of high purity and have their application areas within and outside the ceramics industry.

Samarium was discovered in 1879 by the French chemist Paul Émile Lecoq de Boisbaudran and named after the mineral samarskite where it was isolated from. It has no significant biological role and is only slightly toxic. One of the most important applications of samarium is in samarium-cobalt magnets, these magnets are found in small motors, headphones, high-end magnetic pickups for guitars and related musical instruments. Another important application of samarium and its compounds is as catalyst and chemical reagent. In its usual oxidized form, samarium is added to ceramics and glasses where it increases absorption of infrared light. Radioactive samarium-153 is used to kill cancer cells in the treatment of lung cancer, prostate cancer, breast cancer and osteosarcoma. Samarium-doped calcium fluoride crystals were used as an active medium in one of the first solid-state lasers designed and constructed by Peter Sorokin and Mirek Stevenson at IBM research labs in early 1961.

Selenium is a nonmetal, chemically related to sulfur and tellurium, and rarely occurs in its elemental state in nature. It conducts electricity better in the light than in the dark, and is used in photocells. It is found in economic quantities in sulfide ores such as pyrite, partially replacing the sulfur in the ore matrix. The chief commercial uses for selenium today are in glass making and in chemicals and pigments. Uses in electronics, once important, have been supplanted by silicon semiconductor devices. It is used widely in vitamin preparations and other dietary supplements, in small doses. Some livestock feeds are fortified with selenium as well. It is used in the toning of photographic prints. Selenium is a catalyst in many chemical reactions and is widely used in various industrial and laboratory syntheses, especially organoselenium chemistry. It is also widely used in structure determination of proteins and nucleic acids by X-ray crystallography.

Selenium Dioxide

Selenium dioxide is one of the most frequently encountered compounds of selenium. It is an important reagent in organic synthesis. It imparts a red colour to glass: it is used in small quantities to counteract the blue colour due to cobalt impurities and so to create colourless glass. In larger quantities, it gives a deep ruby red colour. It is the active ingredient in some cold-blueing solutions. It is also used as a toner in photographic developing.

Silica Glass

Silica glass is used as an envelope for halogen lamps, which must operate at a high envelope temperature to achieve their combination of high brightness and long life.
