Refractory ceramic product and manufacturing technology thereof

Abstract

The invention provides a refractory ceramic product and a manufacturing technology thereof and relates to the technical field of ceramics. The refractory ceramic product comprises 200-350 weight parts of blanks, 50-100 weight parts of glazes and 20-40 weight parts of auxiliaries. The raw material composition and the manufacturing technology of the refractory ceramic product provided by the invention are both strictly controlled; at the aspect of the raw materials, blanks, glazes and auxiliaries are reasonably prepared, so that the roasted ceramic product has excellent high temperature resistance, chemical stability, hardness and toughness; at the aspect of the technology, an once-firing manner is adopted for roasting the ceramic, so that the shovel strength is increased and the cost is lowered; besides, a method for gradually increasing temperature and roasting in stages is adopted for roasting, so that the cracking and uneven surface caused by the rapid loss of the ceramic water can be avoided, the yield of the product can be greatly increased and the refractory ceramic product is worthy of popularization in the market.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of ceramics, in particular to a high-temperature-resistant ceramic product and a manufacturing process thereof. [0003] 【Background technique】 [0004] China is one of the first countries in the world to use ceramics. Because of its hard texture, fineness, high temperature resistance, and rich glaze colors, ceramics are widely used in food utensils, decoration, science and other fields. Ceramics is a general term for pottery and porcelain. Most of the ceramic materials are oxides, nitrides, borides and carbides.

Problems solved by technology

Ceramics is a general term for pottery and porcelain. Most of the ceramic materials are oxides, nitrides, borides and carbides. Common ceramic materials include clay, alumina, kaolin, etc. There are many types of ceramic products, mainly divided into daily-use ceramics , architectural ceramics, sanitary ware ceramics and special ceramics, etc., generally choose different raw materials for firing according to different types of ceramics. Due to the lack of ingredients in ceramic products, although they have the advantage of high hardness, their toughness is relatively high. Poor, high temperature resistance needs to be improved

[0005] At present, the production cost of existing ceramic products with high temperature resistance and excellent performance is relatively high, and their popularization is limited. Therefore, the ceramic raw materials are reasonably matched and the manufacturing process is strictly controlled to obtain a high temperature resistance and superior performance. Ceramic products are particularly important
