Preparation and performance improvement method of anorthite/gehlenite multiphase ceramic
The invention discloses a preparation and performance improvement method of anorthite/gehlenite multiphase ceramic, and the ceramic raw material comprises the following components by mass: 9.6-44.0 wt% of CaO, 27.9-44.9 wt% of SiO2, and 14.0-24.4 wt% of Al2O3; the method comprises the steps of adding water according to a water-solid ratio of 0.02-0.20, and performing stirring, pelletizing througha pelletizing disc, naturally curing and drying, and finally performing calcining to obtain the required ceramic. The ceramic prepared by the method can effectively solve the problems of environmentalharm and land occupation caused by industrial solid wastes, and the method has the advantages of wide and accessible raw material, simple preparation technique and low production cost, and has certain economic and social benefits. The invention further discloses a method for improving the performance of the anorthite/gehlenite multiphase ceramic, and a ceramic product with relatively high porosity and enough strength is prepared by externally doping a pore-forming agent.
本发明公开了一种钙长石/钙铝黄长石复相陶瓷的制备及性能改良方法，该陶瓷原料中各组分的质量百分比为：CaO9.6‑44.0wt%，SiO227.9‑44.9wt%，Al2O314.0‑24.4wt%，按照水固比0.02‑0.20加水搅拌，经过成球盘成球，自然养护，烘干，最后煅烧制得所需陶瓷。利用该方法制备陶瓷可有效解决工业固体废弃物对环境危害及土地占用问题，并且该法原料广泛易得，制备工艺简单，生产成本低廉，具有一定的经济效益，社会效益。本发明还公开了一种钙长石/钙铝黄长石复相陶瓷的性能改良方法，通过外掺增孔剂，从而制备出既有较高的气孔率又保持足够的强度的陶瓷制品。
