Problems solved by technology

[0003] 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 white cloud pottery green body, which is made by firing a base material and additives in a multi-component composite solvent system. ~1wt%, pyrophyllite 5~6wt%, low temperature sand 12~25wt%, lithium china stone 3~8wt%, dolomite 5~12wt%, black talc 6~12wt%, limestone 6~10wt%, diopside 8~ 15wt%, Yongchun coarse soil 0-5wt%, waste porcelain powder 0-5wt%; the additive is organosilicon nano liquid, and its weight percentage relative to the base material is 1-3%. In the present invention, by adding multi-element composite flux, especially the addition of lithium element and organosilicon nano-liquid, the firing temperature is greatly reduced, and since the organosilicon nano-liquid forms mullite crystals at low temperature, lithium element is easy to form when firing at low temperature The high-strength glass phase improves the strength of the green body and is easy to degrade.

Description

technical field [0001] 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 [0002] 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 moisture, and finally decompose into soil, while other hard porcelains do not have this function. Therefore, Baiyun pottery is taken from the underground soil. It becomes soil again, which belongs to environmental protection ceramic products. [0003] However, many manufac...
