Heat-resistant high-strength low-expansion ceramic and preparation method thereof
The invention discloses heat-resistant high-strength low-expansion ceramic which comprises the following raw materials in percentage by mass: 15-25% of Guizhou soil, 15-25% of Zhangzhou soil, 3-7% of Xinyang soil, 10-14% of Datong soil, 8-12% of quartz powder, 4-6% of waste porcelain powder, 2-4% of talcum powder and the balance of spodumene. The high-temperature-resistant coating further comprises activated graphite, alpha-aluminum oxide, zirconium oxide, tungsten trioxide, silica sol and an ammonium salt type cationic surface active agent. The mass ratio of the activated graphite to the alpha-aluminum oxide to the zirconium oxide to the tungsten trioxide to the silica sol to the ammonium salt cationic surfactant to the Guizhou soil is (1-5): (1-6): (1-2): (1-3): (1-3): (1-2): (15-25). The invention discloses a preparation method of the heat-resistant high-strength low-expansion ceramic. The invention discloses application of the heat-resistant high-strength low-expansion ceramic to kitchen utensils.
