Foamed ceramic filter plate for purifying high-cleanliness molten aluminum and preparation method of foamed ceramic filter plate
The invention relates to the technical field of functional ceramic and metal melt filtration and purification, and discloses a foamed ceramic filter plate for purifying high-cleanliness molten aluminum and a preparation method of the foamed ceramic filter plate. The phases of the foamed ceramic filter plate comprise kyanite, mullite, quartz and aluminum borate; the proportion of the kyanite is 30-50% of the mass of the foamed ceramic filter plate, the proportion of the mullite is 20-40% of the mass of the foamed ceramic filter plate, the proportion of the quartz is 10-25% of the mass of the foamed ceramic filter plate, and the proportion of the aluminum borate is 10-40% of the mass of the foamed ceramic filter plate. The foamed ceramic filter plate provided by the invention has the advantages of smaller volume density, lower thermal expansion coefficient and lower firing temperature, the production cost is reduced, and the stability in the use process is improved.
本发明涉及功能陶瓷和金属熔体过滤净化技术领域，公开了一种高洁净铝液净化用泡沫陶瓷过滤板及其制备方法；所述泡沫陶瓷过滤板的物相包括蓝晶石、莫来石、石英、硼酸铝；蓝晶石的比例为泡沫陶瓷过滤板质量的30‑50％、莫来石的比例为泡沫陶瓷过滤板质量的20‑40％、石英的比例为泡沫陶瓷过滤板质量的10‑25％、硼酸铝的比例为泡沫陶瓷过滤板质量的10‑40％。本发明的泡沫陶瓷过滤板具有更小的体积密度、较低的热膨胀系数、较低的烧成温度，降低了生产成本、提高了使用过程的稳定性。
