Abstract

The invention discloses a ceramic green body additive capable of reducing firing temperature as well as a preparation method and application thereof. The additive comprises the following components in parts by weight: 35-45 parts of potassium feldspar, 30-36 parts of quartz, 4.0-6.0 parts of kaolin, 2.0-6.0 parts of talc, 18-25 parts of lithium feldspar and 0.5-1.5 parts of lanthanum oxide. By adopting the additive, the firing temperature can be reduced by 50-70 DEG C, and the density and mullite crystalline phase quatity of the ceramic green body are basically constant; and under the condition that the glass phase content is slightly increased, the good thermal shock resistance of the product can be maintained. The additive provided by the invention is characterized in that the energy-saving effect is obvious, and the product can still have high quality and good application prospect.

Description

technical field [0001] The invention relates to a body glaze formula in the daily-use ceramic industry, in particular to a ceramic body additive for lowering firing temperature and its preparation method and application. Background technique [0002] The ceramic industry is a high-energy-consuming industry, especially the daily-use ceramic industry. The firing temperature is high, the firing time is long, and the energy consumption is particularly large. Daily-use ceramic products can be divided into three categories according to the firing temperature: high-temperature ceramics, medium-temperature ceramics and low-temperature ceramics. Secondly, the price of low-temperature ceramics is lower. In order to reduce energy consumption, many manufacturers of daily-use ceramics add pure flux raw materials to the green body, reducing the maximum firing temperature from about 1360°C to about 1270°C, and the energy consumption is also reduced accordingly. However, pure flux Non-tox...
