Problems solved by technology

The existing technical ceramic mud is divided into two types: one is made of single clay with high plasticity, and the other is formula mud, which is generally made by wet ball milling of feldspar, quartz, kaolin, china clay and other raw materials; The sintering temperature of the technical ceramic slurry prepared by these two traditional formulas is as high as 1300-1350°C, and the sintering time is longer, and the energy consumption in the sintering process is larger; on the other hand, the loss of ignition rate is high, and the product is easy to sinter. Deformation, the strength of the fired product is also low; in addition, the whiteness of the fired craft product is not enough, it turns dark yellow, which affects the appearance

Abstract

The invention discloses a slurry for craft ceramic and a composition for preparation of the slurry. The composition comprises the following matters in parts by weight: 40 to 60 parts of washed clay, 5 to 10 parts of kaolin, 3 to 8 parts of ball clay, 3 to 5 parts of potassium feldspar, 3 to 5 parts of lithium feldspar, 10 to 15 parts of dolomite, 8 to 15 parts of diopside and 0.01 to 0.03 part of cobalt blue. The slurry prepared from the composition provided by the invention has the advantages of low sintering temperature, short sintering time, low energy consumption, and high product strength and whiteness.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a combination formula of technological ceramic mud. Background technique [0002] Craft ceramics is a kind of art that can be viewed and played; it can be used, invested and collected. With its exquisite decoration, dreamy artistic conception, pottery personality and unique material, It has formed a unique ceramic culture and has been loved by people. The existing technical ceramic mud is divided into two types: one is made of single clay with high plasticity, and the other is formula mud, which is generally made by wet ball milling of feldspar, quartz, kaolin, china clay and other raw materials; The sintering temperature of the technical ceramic slurry prepared by these two traditional formulas is as high as 1300-1350°C, and the sintering time is longer, and the energy consumption in the sintering process is larger; on the other hand, the loss of ignition rate is high, and the product i...
