Crystalline layered sodium silicate
A crystalline layered sodium silicate with the formula xNa2O.ySiO2.zP2O5 (I) is new. x:y = 0.35 - 0.6, x:z = 1.75 - 1200 and y:z = 4 to 2800. Also claimed is a method of producing (I) by mixing a phosphorus cpd. with a silicate in an aq. medium; causing it to react; partially removing the water; and...

Summary: | A crystalline layered sodium silicate with the formula xNa2O.ySiO2.zP2O5 (I) is new. x:y = 0.35 - 0.6, x:z = 1.75 - 1200 and y:z = 4 to 2800. Also claimed is a method of producing (I) by mixing a phosphorus cpd. with a silicate in an aq. medium; causing it to react; partially removing the water; and calcining it. |
