Abstract

The invention belongs to the field of ceramic materials, and relates to a petalite heat-resisting ceramic material with strong forming stability. The petalite heat-resisting ceramic material is prepared by combining and sintering petalite, bauxite, quartz, kaolin and waste porcelain powder which are utilized as main raw materials. The ceramic material provided by the invention is characterized by being prepared from the following raw materials in parts by weight: 20-45 parts of petalite, 8-15 parts of bauxite, 2-6 parts of quartz, 20-32 parts of ordinary kaolin, 2-4 parts of aluminum oxide, 10-20 parts of lime mud (or named as 'Guangxi Beihai mud'), 2-5 parts of magnesium soil, 5-10 parts of waste porcelain powder, and 0.3-0.6 parts of carboxymethylcellulose. The petalite heat-resisting ceramic material provided by the invention has the advantages that an effect that the ceramic material does not crack under the condition of quick cooling at 480 DEG C-20 DEG C can be achieved, the forming stability is good in the process of production, the merit factor of products can reach over 90%, and a ceramic pot product is clean and easy to wash; and meanwhile, the petalite heat-resisting ceramic material has the beneficial effects of white product, good texture, glossiness, no blemish, and the like.

Description

Technical field [0001] The invention belongs to the field of ceramic materials and relates to a lithium-permeable heat-resistant ceramic material with strong molding stability. Background technique [0002] Spodumene is a framework silicate mineral with Mohs hardness of 6 to 6.5, density of 2.3 to 2.5g / cm3, and brittleness; it is mainly produced in granite pegmatite, and is combined with spodumene, pollucite, and color Tourmaline and other symbiosis can be used as ceramic raw materials. At present, in the field of domestically produced heat-resistant porcelain, the production technology of replacing spodumene with permeable feldspar as the main raw material is becoming more and more perfect, such as "permeable feldspar / cordierite composite low-expansion ceramic and its preparation method" CN200710129302 .9. Taking laphurite, kaolin, talc, etc. as raw materials, using ordinary ceramic sintering method to generate low-expansion ceramics with composite laphurite / cordierite complex ...
