Aluminum titanate material, preparation method thereof and ceramic material with aluminum titanate material
The invention discloses an aluminum titanate material which comprises the following components in percentage by mass: 40-45% of alumina powder; 35-40% of titanium dioxide; mgCO3: 10%-20%; znO: 3 to 5%; and 2 to 4 percent of Fe2O3. The invention also discloses a preparation method of the aluminum titanate material, and also discloses a ceramic material containing the aluminum titanate material. According to the aluminum titanate material provided by the invention, aluminum titanate with high corrosivity and a low-expansion principal crystalline phase is provided by adopting Al2O3 and TiO2, when ZnO and Fe2O3 are in a specific proportion and MgCO3 in a specific proportion is combined, the reaction temperature and the reaction time of the aluminum titanate material can be effectively reduced, and the prepared aluminum titanate material is sintered for 2 hours at the temperature of 1400 DEG C; and the mechanical strength of the prepared aluminum titanate sintered body is greatly improved, and the inherent low thermal expansion coefficient and corrosion resistance of the aluminum titanate sintered body cannot be lost.
本发明公开了一种钛酸铝料，以质量百分比计，其包括如下组分：氧化铝粉：40‑45％；钛白粉：35‑40％；MgCO3：10‑20％；ZnO：3‑5％；Fe2O3：2‑4％。本发明还公开了一种钛酸铝料的制备方法，同时还公开了含有该钛酸铝料的陶瓷材料。本发明所提供的钛酸铝料，通过采用Al2O3与TiO2提供了高腐蚀性且低膨胀主晶相的钛酸铝，且当ZnO和Fe2O3在特定比例时，结合特定比例的MgCO3时，其可有效降低钛酸铝料的反应温度和反应时间，制备出的钛酸铝料在1400℃的温度下烧结2h；且制备的钛酸铝料烧结体不仅机械强度被极大改进，且不会损失钛酸铝烧结体所固有的低的热膨胀系数和耐腐蚀性能。
