The improved anti-oxidation property of graphite materials dealt with the water-soluble impregnant
Abstract: The paper evaluates the effects of phosphorylation series antioxidants through the post-impregnation of graphite materials treated with soluble antioxidative impregnants made from water-soluble Al(H2PO4)3, Mg(H2PO4)2, boric acid and sodium hexametaphosphate. It is shown that the initial oxidation temperature of graphite materials dealt with the water-soluble impregnant rise from 400 ℃ to 500 ℃, and…
