any of various silicon compounds that contain carbon and hydrogen, are obtained as oily or greasy substances or plastics, and are used especially for water-resistant and heat-resistant lubricants and varnishes silicatenoun a chemical salt that consists of a metal combined with silicon and oxygen and...
Emerald is composed of aluminum and beryllium silicate and a small amount of chromium that imparts the green color to the stone. 绿柱玉是一种含铝和铍的硅酸盐,因含少量的铬而呈翠绿色,比石英稍为坚硬,通常呈粒状或明显的六方晶体形态。 jw2019 i. Nutrients (silicate, nitrate, phosphate 一...
Non-silicates refer to compounds that are not composed of silicon and oxygen, and are analyzed using specific methods like the one described by Anbar & Guttmann (1959). AI generated definition based on:Handbook of Stable Isotope Analytical Techniques,2009 ...
In addition to the Brønsted acid sites band erosion, the formation of a complex absorption composed of a peak centered at 3440 cm− 1 and a large shoulder at 3496 cm− 1 occurs and is attributed to the stretching of Br0nsted acid sites interacting with CO. At lower CO pressures, ...
Substantially dust-free agglomerates of a crystalline alkali metal silicate of substantially uniform size are prepared by mixing at least an equal amount by weight of a solid chemically similar alkali metal silicate (defined as chemical compounds composed of alkali metals, silicon, and oxygen in ...
