Embodiment 1

[0018] Take 62 grams of talc, 56 grams of albite, 4 grams of potassium feldspar, and 1.5 grams of barium carbonate, put them into a grinder for grinding and mixing, and pass through a 60-mesh sieve to obtain powder. Put the mixed powder into the electric melting furnace for melting, and keep it warm at 1520°C for 3 hours. After it is completely melted into a uniform liquid, it is fed into the mold of the centrifugal molding machine with a liquid extractor for molding. The microcrystalline ceramic matrix is ​​obtained by annealing in the furnace, and the chemical composition of the obtained microcrystalline ceramic matrix is ​​(in terms of moles): 0.06K 2 O, 0.92Na 2 O, 0.43CaO, 1.0Al 2 o 3 , 11.3SiO2 2 , 3.9MgO, 0.07BaO, put it on the imitation refractory kiln furniture coated with quartz coating, and then place the microcrystalline ceramic matrix and imitation refractory kiln furniture in the automatic control gradient electric furnace as a whole to keep the temperature ri...

Embodiment 2

[0022] Get 60 grams of talc, 56 grams of albite, 7 grams of potassium feldspar, and 0.3 grams of barium carbonate. Other conditions are the same as in Example 1. The chemical composition of the obtained microcrystalline ceramic matrix is ​​(in moles): 0.1K 2 O, 1.0Na 2 O, 0.45 CaO, 1.0 Al 2 o 3 , 12.3SiO2 2 .

[0023] .

Embodiment 3

[0025] The chemical composition of the microcrystalline ceramic matrix is ​​the same as in Example 1, and it is placed on the imitation refractory kiln furniture coated with quartz coating, and then the microcrystalline ceramic matrix and the imitation refractory kiln furniture are placed in an automatic control In a gradient electric furnace, heat treatment is carried out. The heat treatment parameters are as follows: heating up to 900°C at 5°C / min, holding for 2 hours, then raising the temperature to 1000°C at 1°C / min, holding for 2 hours, taking it out and quenching to 650°C, and then cooling naturally to room temperature to obtain Microcrystalline ceramic products for daily use.

Abstract

The invention relates to microcrystalline domestic ceramic prepared by talcum. By taking the raw material components and the component contents thereof take 100 g of microcrystalline ceramic body as reference, the mass in gram of each component is as follows: 55-65 g of talcum, 50-65 g of soda feldspar, 4-15 g of potassium feldspar and 0.2-1.8 g of barium carbonate. The microcrystalline domestic ceramic prepared by talcum disclosed by the invention has the following advantages that: 1) cost is low, and the problems of the process properties of common ceramic production process necessary for clay and the supply bottleneck of high-quality kaolin are thoroughly solved; 2) automatic production process for glass is used for replacing manual and semi-mechanized processes for domestic ceramic, so that production efficiency is greatly increased and quality is greatly stabilized; and 3) the various performances and appearance quality requirement of domestic ceramic are realized via special heat treatment method.

Description

technical field [0001] The invention relates to a microcrystalline daily-use ceramic prepared from talc. Background technique [0002] Since the 1950s, many countries have studied the preparation method of glass-ceramics, such as Corning Corporation of the United States and the French Bow and Arrow Company. The main raw material used is industrial slag, and the products are mainly decorative plates. In the 1980s, it gradually began to use chemical raw materials to make catering utensils. This technology entered China in the 1990s, and began to produce transparent glass tableware and opal glass tableware on an industrial scale until now. However, its product performance and appearance are all glass products, which are far from daily-use ceramic products. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a microcrystalline daily-use ceramic prepared from talc in view of the above-mentioned prior art. In the thermop...
