High-strength magnesium jade porcelain and manufacturing method thereof

Abstract

The invention provides a high-strength magnesium jade porcelain, and relates to the technical field of ceramics. The blank of the magnesium jade porcelain comprises the following raw materials by weight: 30-50 parts of black talc modified washing mud, 30-40 parts of a black talc calcined material, 10-20 parts of kaolin and 5-10 parts of a mineralizer. The method comprises the steps of adding 0.1-0.2% of a chelating agent into black talc, grinding, and sequentially carrying out screening, impurity removal, iron removal and dehydration treatment to obtain black talc modified washing mud; and calcining the black talc modified washing mud to obtain the black talc calcined material. The main crystal phase of the high-strength magnesium jade porcelain is a high-strength crystal structure formed by compounding protoenstatite and cordierite. The appearance quality and the product performance are superior to those of bone china and magnesia china, the strength is high, the whiteness is good, and the transparency is good. The raw materials black talc, lithium chinastone and kaolin used in the manufacturing method are rich in resource, high in quality and low in cost.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-strength magnesia jade porcelain and a manufacturing method thereof. Background technique [0002] As early as more than two hundred years ago, the British invented bone china with animal bone carbon as the main raw material and Ca3PO4 as the main crystal phase. At present, bone china is recognized as a high-grade porcelain in the world. Its color is as white as jade, the glaze is moist and bright, the carcass is transparent and flawless, and the porcelain is highly regular. To this day, there is still no porcelain that can compare with it. Talc porcelain was invented in Shandong, my country in the 1980s. Its whiteness and transparency are comparable to those of bone china. However, due to its poor process performance, narrow firing range, and late aging, the three major bottlenecks are difficult to overcome and have not been industrialized. promote.

Problems solved by technology

In the 1980s, Shandong, my country invented talc porcelain. Its whiteness and transparency are comparable to those of bone china. However, due to its poor process performance, narrow firing range, and late aging, the three major bottlenecks are difficult to overcome and have not been industrialized. to promote

[0003] At present, my country's bone china production industry is affected by factors such as the tight supply of bone carbon as the main raw material and the soaring price, and the production is unsustainable.
