Abstract

The invention discloses a preparation method for a calcium magnesium aluminum crystal complex material. The preparation method comprises the following steps: dissolving calcium magnesium carbonate mineral powder in deionized water to obtain an aqueous magnesium carbonate mineral solution; then adding hydrochloric acid into the aqueous magnesium carbonate mineral solution to obtain a reaction solution; adding AlCl3.6H2O into deionized water to obtain an aqueous solution of AlCl3; adding the obtained aqueous solution of AlCl3 into the obtained reaction solution, and carrying out a reaction at 150 to 200 DEG C under the action of an alkaline substance for 12 to 48 h; and subjecting a reaction mixture to post-treatment to obtain the calcium magnesium aluminum crystal complex material. The method of the invention is a novel, environment-friendly and convenient process with low energy consumption; and the method uses natural calcium magnesium carbonate minerals as a main reactant, and a functional aluminum source is added to convert the minerals into the useful calcium magnesium aluminum crystal complex material, so natural calcium magnesium carbonate minerals can be innovatively and effectively utilized for production of new materials.

Description

(1) Technical field

[0001] The invention belongs to the technical field of mineral materials and chemistry, and in particular relates to a method for converting natural calcium magnesium carbonate minerals into calcium magnesium aluminum crystal composite materials. (2) Background technology

[0002] Calcium magnesium carbonate mineral is an important geological sedimentary rock, in which calcium magnesium carbonate MgCa(CO 3 ) 2 Form rock minerals (CaO and MgO contents approximately 29.5 wt% and 20.7 wt%, respectively). Magnesium-calcium carbonate minerals can be formed in many different geological environments, usually as substitutes for limestone, and are also an important part of oil storage rocks (containing alkali metals and fresh water), with the advantages of non-toxicity and low cost. Dolomite can be used as furnace repair materials and refractory bricks. At the same time, it can be added to the glass to increase the weather resistance of the glass and prevent cr...
