Aluminium, the third most abundant element in the earth’s crust, occurs in nature in combination with silicon and oxygen (i.e. as aluminium silicate). When subject to tropical weathering, aluminium silicate may react to form aluminium hydroxide. Rock containing high concentrations of aluminium hydroxide is called bauxite. This rock is the usual starting material for the production of aluminium....

Abstract The experiment was conducted in the fields of horticulture and Garden Engineering at College Agriculture - University Kerbala for agricultural season 2022-2023 with aim knowing effect spraying silicon form potassium silicate (K2Sio3) adding by-product (whey) improving growth indicators Chinese Cabbage plant. included 16 treatments that four concentrations (0.1.2.3) ml L-1 whey (0.8.16....

abstract in order to study the effects on salinity and silicon application on yield and yield components of purslane (portulaca oleracea l.), an experiment was conducted in a completely randomized desgin with three replications and two factors consisted of four different levels of salinity using nacl (0, 7, 14, 21ds/m) and two levels of silicon (application of one mmol sodium silicate and not a...

The recent discovery that pentacoordinate alkali glycolato silicates such as monomeric MSi(OCH,CH,O),OCH,CH,OH or dimeric M,Si,(OCH,CH,O), (where M = Li, Na, K, or Cs) can be synthesized directly from SO,, ethylene glycol, and MOH suggests that these compounds may serve as useful, inexpensive precursors to alkali silicate glasses or ceramics, either by sol-gel processing or by simple pyrolysis....

ince the early 1970s, scientific evidence has shown that silicon is an essential nutrient for higher animals, including humans. Its role in human physiology is not fully defined, but it appears to be required for optimal growth and development of bone, cartilage, and connective tissues. Both metabolic and structural roles have been proposed. In bone, silicon is localized in active growth areas ...
