Problems solved by technology

[0004] Due to the single composition of traditional high-temperature-resistant ceramic materials, there are obvious deficiencies in properties, and high-temperature-resistant ceramic materials have disadvantages such as processing difficulties, poor thermal shock resistance, and difficulty in bonding. Therefore, the industry has begun to study new high-temperature-resistant ceramic materials and low-temperature heat resistant material

Abstract

The invention discloses low-temperature heat-resistant ceramics and production technology thereof. The low-temperature heat-resistant ceramics comprise, by mass percentage, 36-42% of lithionite, 24-30% of alumina, 30-32% of Longyan kaolin, and 2-4% of bentonite. The ceramics are prepared by pre-pulverizing the raw materials, performing wet ball-milling through a ball mill, performing screening and magnetic separation to remove iron impurities, performing moulding, finishing and biscuit firing, performing spraying with bright glaze through color painting for glaze firing, and performing packaging and warehousing. Bright glaze is adopted in the production technology, and the produced ceramics are good in quality, bright in color, and stable in performance. The firing temperature is low, a large amount of heat is saved, and therefore energy consumption can be reduced by 30%. Fuel consumption and cost is saved, and the production technology has a significant function on energy conservation and emission reduction.
