Chromium carbide. A typical example of a carbide compound that combines the refractory and hardness of carbides with some other property attributable to the cation. In this case, the anti-corrosive properties of chromium. Chromium carbide is used extensively in aerospace materials, high temperature drilling parts, welding electrodes and in other high temperature corrosive environments. Hafnium carbide. Combining the high refractive index of both the element hafnium and of carbides generally, hfc is the most refractory simple binary compound with a melting temperature of 3, 890 ºc. Tungsten carbide. The most commonly used of the carbides is tungsten carbide which when combined with cobalt carbide and/or titanium carbide, niobium carbide, chromium carbide and tantalum carbide produces the hardest and least costly cutting drills and tools. Zirconium carbide. Another one of the refractory group of metals, zirconium, generally finds applications in its oxide form in ceramic materials and as the carbide also has many potential uses in hard heat resistant ceramics. It has the additional characteristic of being electronically conductive.

Molecular formula: C22H18O11 Molecular weight: 458.38 CAS No.: 989-51-5 Product Spec.: EGCG 90% Physiological Functions Modern research and scientific data demonstrates that the beneficial effects of green tea are largely due to its main catechin, Epigallocatechin Gallate (EGCG). EGCG makes up about 30%-50% of the total catechin content and has an antioxidant activity about 25-100 times more potent than Vitamin C and E. Recent research has also indicated that there may be positive effects of EGCG in the field of disease risk reduction regarding cancer and cardiovascular disease. Further research has revealed additional findings where green tea, green tea extract and its constituents can also contribute: Product characteristic *A very pure and refined off-white compound with strong healthy function, which can be added to a broad range of dietary supplements, food products and beverages without a major impact on their color and taste. * Much cheaper than other companies price with the same quality.
