Calcium oxalate crystals (CaC 2 O 4 ·H 2 O) have a molecular weight of 128.096 g mol −1 in anhydrous form, of which calcium represents c . 30%. However, plant crystals have varying degrees of hydration, which reduces slightly the proportion of calcium.
Abstract Extracellular Ca 2+-influx induced by trivalent metal ions (Fe 3+, Al 3+, Cr 3+, In 3+, Ga 3+, and La 3+) in Ehrlich carcinoma cells is enhanced by ATP.This action seems to be related to the high coordination capacity of the ATP ligand that inhibits the polymerization of the solvated ions taking place at physiological pH, and consequently permits their biological activity.

Other high quality greases use metal to metal to generate the temperature 90 to 130 C necessary to activate the chemical E.P. used in boundary lubriion protection. Grease’s E.P. solids offer the advantage of giving a continuos E.P. action irrespective of temperature and long before boundary lubriion conditions occur.
SiO 2 + C -----> Si + CO 2 La silice est mélangée avec un réducteur tel que le coke, et porté à très haute température entre 1 500 et 3 000° C dans des fours à arc. Le silicium, recueilli dans des poches, est affiné par injection d’air pour éliminer les traces d’aluminium et de calcium, puis coulé ou granulé.
