Problems solved by technology

[0004] However, many manufacturers develop and strengthen Baiyun clay. In order to improve the mechanical strength of Baiyun pottery, increase the firing temperature (1080°C-1130°C) to achieve semi-ceramic, which reduces the degradation function of Baiyun pottery, and does not meet the energy-saving and emission reduction requirements of Baiyun pottery. Purpose
There are also research patents that increase the compressive stress of the glaze to increase the strength, and the firing temperature also reaches 1080±15°C. Generally, the glaze is in a state of compressive stress, and the method of increasing the strength by increasing the compressive stress is unreliable and difficult to control. , poor control will reduce the strength of Baiyun pottery

Abstract

The invention discloses a low-cost high-strength light-weight ceramic body and a preparation method thereof. The low-cost high-strength light-weight ceramic body is prepared by firing a base materialand an additive in a multi-element compound flux system, wherein the additive is an organosilicon nanometer fluid, and the base material comprises the following raw materials by weight percentage: 28-30 wt% of elutriating mud, 12-14 wt% of smolmitza, 0-1 wt% of bentonite, 5-6 wt% of pyrophyllite, 12-18 wt% of low-temperature sand, 4-5 wt% of lithium chinastone, 6-10 wt% of dolomite, 6-8 wt% of black talc, 7-8 wt% of limestone, 8-10 wt% of diopside, 0-2 wt% of Yongchun coarse soil and 0-3 wt% of waste porcelain powder. A multi-element compound flux is added, particularly that the lithium element and the organosilicon nanometer fluid are added, so that the firing temperature is reduced substantially, the organosilicon nanometer fluid forms a mullite crystal at low temperature, and the lithium element forms a high-strength glass phase easily when being fired at the low temperature, so that the strength of the ceramic body is improved, and the ceramic body is easy to degrade.

Description

[0001] This application is a divisional application of a patent application entitled "A Low-Cost High-Strength White Cloud Ceramic Body and Its Preparation Method". The filing date of the original application is 2016-04-30, and the application number is 201610277068.3. technical field [0002] The invention relates to the technical field of ceramic products, in particular to a low-cost, high-strength dolomite body and a preparation method thereof. Background technique [0003] Baiyun pottery, also known as lightweight ceramics, is an environmentally friendly ceramic product recognized in the international market. Lightweight white cloud pottery can be painted with colored glazes, and can be made into various types of utensils, such as tea tableware, handicrafts, etc. It has a beautiful appearance and is favored by consumers. In particular, due to the high water absorption rate of Baiyun pottery, after the broken tiles are buried in the ground, they are easily degraded by moi...
