Manufacturing method of high-strength foamed ceramic
The invention provides a manufacturing method of high-strength foamed ceramic, which comprises the following steps: adding multiphase toughening powder into a widely-known foamed ceramic raw materialtaking silicon carbide as a foaming agent, uniformly mixing, and sintering at 1150-1200 DEG C to obtain the foamed ceramic, wherein the mass ratio of the foamed ceramic raw material to the multiphasetoughening powder is 100:10-30; The multiphase toughening powder is a mixture of at least three of mullite, cordierite, zirconium oxide and high-alumina fibers. The foamed ceramic prepared by the method provided by the invention is high in compressive strength, has thermal stability, fire resistance and heat insulation superior to those of the existing product, can expand the application scene ofthe foamed ceramic, and has a positive effect on the development of the foamed ceramic industry.
本发明提供一种高强度发泡陶瓷的制造方法，在公知的以碳化硅为发泡剂的发泡陶瓷原料中加入多元相增韧粉体，混合均匀后，经1150℃～1200℃烧结获得发泡陶瓷，所述发泡陶瓷原料与所述多元相增韧粉体的质量比为100：10～30；所述多元相增韧粉体为：莫来石、堇青石、氧化锆、高铝纤维中至少3种的混合。通过本发明提供方法制造的发泡陶瓷，抗压强度高，而且热稳定性、耐火性和隔热性均优于目前产品，这种高强度发泡陶瓷可以拓展发泡陶瓷的应用场景，对发泡陶瓷产业发展壮大具有积极作用。
