Phosphates
Phosphates can be effective flame retardants. (RDC 7/20/2009) “A phosphate, an inorganic chemical, is a salt of phosphoric acid. Inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry.[1][2] In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. The phosphate ion is a polyatomic ion with the empirical formula PO43− and a molar mass of 94.973 g/mol. It consists of one central phosphorus atom surrounded by four identical oxygen atoms in a tetrahedral arrangement.” (Wikipedia 7/20/2009)
