Abstract

The invention discloses a low-temperature rapid-sintering reinforced ceramics, which is characterized by the following: adopting composite catalyst to accelerate crystal to grow into ceramics within 30-45 min under 1000-1030 deg.c; obtaining the sintering temperature of national and international ceramics between 1150 and 1360 deg.c and fastest sintering time between 1 and 4h.

Description

technical field [0001] The invention relates to a formula, which changes the traditional medium and high temperature firing method and forms a new low temperature firing method. Background technique [0002] At present, there are two types of firing flames at home and abroad: oxidizing flame and reducing flame. The firing temperature of oxidizing flame is between 1150-1360°C, and the firing temperature of reducing flame is between 1250-1400°C. After adopting the new formula, the firing temperature of low-temperature strengthened porcelain fired with oxidizing flame is only 1000-1030°C, and the porcelain color after firing is neither blue-white like that fired by reducing flame nor fired by oxidizing flame. It is yellowish white, but milky white in between, with high transparency and a natural and elegant quality. At the same time, the mechanical strength of products fired by this method is between 180-220Mpa. Contents of the invention [0003] The main content of the pre...
