Mid-lower-temperature sintering daily talc ceramic and production method thereof

Abstract

The invention belongs to the technical field of daily ceramics, in particular to a mid-lower-temperature sintering daily talc ceramic and a production method thereof. The daily talc ceramic comprises the following chemical components: 58-63% of SiO2, 15-20% of Al2O3, 15-20% of MgO, 0.2-4% of K2O, 0.5-1% of Na2O, 0.1-2% of CaO and comprises the following components: 50-55% of talc, 25-30% of kaoline, 15-20% of feldspar and 2-5% of alumina. The daily talc ceramic has a sintering temperature range of 1180-1230 DEG C, uses great amounts of kaoline and feldspar, has the advantages of good molding performance, wide sintering range and low sintering temperature, overcomes the defects of difficult molding, difficult sintering and easy ceramic fracture of the traditional talc ceramic and is easy to popularize and apply.

Description

technical field

[0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a new material of daily-use steatite porcelain and a method for producing the daily-use steatite porcelain. Background technique

[0002] Daily-use talc porcelain is a new type of porcelain developed by Shandong Silicate Research and Design Institute in the 1970s. After the 1970s, domestic porcelain producing areas such as Shandong, Liaoning, and Hebei, as well as Japan abroad, have conducted a lot of research and put into mass production. Daily-use talc porcelain uses talc as the main raw material, and its raw material formula range is generally 70-75% of burnt talc, 10-15% of feldspar, and 12-18% of clay. Talc porcelain is characterized by high whiteness, high strength, good light transmittance, and glossy color, and can be used as fine daily-use porcelain and arts and crafts porcelain. However, the production of daily-use talc porcelain has always been...
