Abstract
Calcium arsenate may be produced by allowing a solution of arsenic acid to act upon lime (quick or slaked), or limestone, the product being dehydrated at 400 to 600 DEG C. By initially proportioning the amount of arsenic acid relative to the lime, the product will be meta- or pyro-arsenate or an intermediate or neighbouring composition.ALSO:A cement comprises calcium meta-arsenate and/or pyro-arsenate or approximately those proportions, together with lime, calcium silicate, Portland cement, aluminate cement or the like. On hydration the meta or pyro arsenate, which may form 20 to 80 per cent of the mixture, combines with lime to form ortho-arsenate. Filling materials may be compounded with the cement. The calcium arsenate may be produced by allowing a solution of arsenic acid to act upon lime, (quick or slaked), or limestone, the product being dehydrated at 400 to 600 DEG C. By initially proportioning the amount of arsenic acid relative to the lime, the product will be meta- or pyro-arsenate or an intermediate or neighbouring composition.
