Abstract

The invention belongs to the field of ceramic materials and relates to a high-lithium heat-resisting ceramic material. The high-lithium heat-resisting ceramic material is formed by combining and sintering petalite, Waring soil, kaolin and waste ceramic powder which are mainly used as raw materials. The high-lithium heat-resisting ceramic material is characterized by comprising the following raw materials in parts by weight: 40-55 parts of petalite, 12-20 parts of Guizhou kaolin, 20-30 parts of Waring soil, 5-10 parts of waste ceramic powder, 6-8 parts of Yichun kaolin, 6-8 parts of Zhongxia soil, 2-4 parts of Zhangzhou black soil, 2-4 parts of talcum powder, 2-4 parts of alumina and 3-6 parts of quartz powder. According to the invention, the produced heat-resisting ceramic pot has good thermal stability, i.e., the produced heat-resisting ceramic pot dose not break under the quenching condition at the temperature of 520 DEG C-20 DEG C; a quality index exceeds a standard requirement of GB / T258-2002; and the thermal stability is better, thus the prepared heat-resisting ceramic pot is longer in service life, is good in cooking effect, is clean and is easy to wash.

Description

technical field [0001] The invention belongs to the field of ceramic materials and relates to a high-lithium heat-resistant ceramic material. Background technique [0002] Lithium feldspar is a framework silicate mineral with a Mohs hardness of 6-6.5, a density of 2.3-2.5g / cm3, and a brittle nature; it is mainly produced in granite pegmatites, together with spodumene, cesium garnet, and colored Tourmaline and other symbiosis can be used as ceramic raw materials. At present, in the field of heat-resistant porcelain produced in China, the production technology of using petalite feldspar instead of spodumene as the main raw material is being improved day by day, such as "petalite / cordierite composite low-expansion ceramics and its preparation method" CN200710129302 .9, using petalite, kaolin, talc, etc. as raw materials, adopting ordinary ceramic sintering methods to produce low-expansion ceramics whose main crystal phase is composite petalite / cordierite composite crystal stru...
