Abstract

The invention is a new type of energy-saving ceramics - low-temperature fast-fired reinforced ceramics. The composite catalyst is used to promote the rapid growth of crystals into porcelain within 30 minutes to 45 minutes at a temperature of 1000-1030°C. At present, the firing temperature of all-ceramic at home and abroad is 1150-1360 ℃, and the fastest firing time is 1 hour to 4 hours. In contrast, low-temperature fast-fired reinforced porcelain reduces the firing temperature and shortens the firing time. At the same time, the product quality is improved. It not only has the whiteness and transparency of bone china, but also has the strength of reinforced porcelain and magnesia porcelain, and has good thermal stability.

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 the low-temperature strengthened porcelain fired with an oxidizing flame is only 1000-1030°C, and the porcelain color after firing is neither the bluish white of the reducing flame nor the 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 the products fired by this method is between 180-220Mpa. Contents of the invention [0003] The main content of the p...
