Foamed ceramic composite additive, foamed ceramic and preparation method thereof
The invention discloses a foamed ceramic composite additive. The foamed ceramic composite additive comprises aluminum oxide and zirconium dioxide. In the foamed ceramic composite additive, the dispersion strengthening effect of aluminum oxide and the phase change toughening effect of zirconium dioxide can be superposed; the aluminum oxide can inhibit grain growth of the zirconium dioxide, and the zirconium dioxide can also inhibit grain growth of the aluminum oxide, so that the strengthening effect is improved. The invention further provides the foamed ceramic, the foamed ceramic is formed by mixing and firing the formula raw materials of the foamed ceramic, the foamed ceramic composite additive containing aluminum oxide and zirconium dioxide and other additives according to a specific proportion, the fire endurance time is prolonged, and the high compressive strength of the foamed ceramic is kept.
本发明公开了一种发泡陶瓷复合添加剂，所述发泡陶瓷复合添加剂包含氧化铝和二氧化锆。本发明提供的发泡陶瓷复合添加剂中氧化铝的弥散增强作用和二氧化锆的相变增韧效果可以叠加；氧化铝能够抑制二氧化锆的晶粒生长，二氧化锆同时也能抑制氧化铝的晶粒生长，提升强化效果。本发明中还提供一种发泡陶瓷，该发泡陶瓷通过将发泡陶瓷配方原料和含有氧化铝和二氧化锆的发泡陶瓷复合添加剂及其他添加剂以特定比例混合烧制而成，耐火极限时间延长的同时保留其高抗压强度。
