Abstract
The invention relates to the technical field of functional materials, in particular to a method of preparing glass ceramics from granite waste residue. The method of preparing the glass ceramics from the granite waste residue includes the following steps that quartz sand, basic magnesium carbonate, aluminum hydroxide and ZrO2 are mixed uniformly, put into a corundum crucible and kept at the temperature for 2 h in a silicon molybdenum rod electric furnace at the temperature of 1600 DEG C, then molten glass is poured onto a preheated steel plate to carry out casting molding, the molded molten glass is fast placed in an annealing furnace at the temperature of 680 DEG C to carry out annealing so as to obtain uniform and transparent basic glass, and then glass ceramics are obtained through the nucleating and crystallization processes. The four-point bending strength of the glass ceramics are 67.35 MPa, and four point bending strength of a sample is gradually improved along with rising of crystallization temperature, and the crystal phase structure is uniform and presents columnar and felt-shaped compact assemblages which are arrayed in a stacked mode.
