Abstract
The invention relates to glass ceramics and a preparation method. At present, although the matching of preparation and a preparation process of the glass ceramics are greatly researched, a series of problems that the preparation cost is high, the price is expensive and the glass ceramics is difficult to compete with other building decoration materials still exist, and a main factor causing the high manufacturing cost is the high raw material cost of the glass ceramics; moreover, the production process is high in energy consumption and low in the rate of finished product. The glass ceramics consists of SiO2, Al2O3, CaO, Fe2O3, K2O, MgO, TiO2, Na2O, wherein the volume fractions are as follows: 30 to 70 percent SiO2; 10 to 30 percent Al2O3; 5 to 15 percent CaO; 5 to 15 percent Fe2O3; 0.5 to 4 percent K2O, 1 to 3 percent MgO, 0.5 to 3 percent TiO2 and 0.5 to 2 percent Na2O. The invention is applied to the glass ceramics and the preparation method.
