Abstract

The invention relates to a cast stone microcrystal plate and belongs to the field of the novel wear-resistant and anti-corrosion material. The invention is characterized in that the cast stone microcrystal plate comprises the following chemical components in percentage by weight: 44 to 53 percent of silicon dioxide; 15 to 20 percent of aluminium oxide; 8 to 18 percent of calcium oxide; 6 to 8 percent of magnesium oxide; and 9 to 16 percent of iron sesquioxide and ferrous oxide. The production process of the invention comprises a melting temperature, a melt condensing temperature before crystallization, a crystallization temperature, a crystallization temperature time, an initial annealing temperature and an annealing rate, wherein the melting temperature is between 1380 and 1420 DEG C; the melt condensing temperature before crystallization is between 800 and 850 DEG C; the crystallization temperature is between 950 and 1,020 DEG C; the crystallization time is between 20 and 30 minutes; the initial annealing temperature is between 650 and 750 DEG C; and the annealing rate is between 150 and 170 DEG C per hour. The thickness of the cast stone microcrystal plate of the invention is between 12 and 18mm to meet the market demand.
