Mixed Calcium and Magnesium Compound and Method for Producing Same

摘要

A method for producing a mixed calcium and magnesium compound comprising the slaking of quicklime with a magnesium hydroxide suspension, forming solid particles, said slaking by non-wet means forming said solid particles comprising a calcium phase and a magnesium phase intimately bonded to each other and of homogeneous volume distribution, and a mixed compound comprising a calcium phase and a magnesium phase.

1. A method for manufacturing a mixed calcium and magnesium compound comprising slaking of quicklime with an aqueous medium, with formation of solid particles,
characterized in that said aqueous medium is a suspension of magnesium hydroxide and in that said slaking is a slaking via a non-humid route, forming said solid particles of a mixed compound of formula xCa(OH)2.yMg(OH)2.zI comprising a calcium phase and a magnesium phase, intimately bound and with a homogenous volume distribution, a formula in which x, y and z are weight fractions with x+y comprised between 88 and 100% by weight based on the total weight of the mixed compound, and in which I represents impurities.
