Porcelain kitchen ware is more and more popular with consumers, in particular to heat-resistant porcelain, which is a ceramic that is not cracked when being dried and burned in air at a certain temperature, the heat resistance degree of the porcelain kitchen ware can reach more than 450 ℃, and some porcelain kitchen ware can even reach 800 ℃, and the demands of safety and burning resistance of consumers can be met.
Spodumene is a common heat-resistant porcelain raw material, has the characteristics of stability and heat resistance, can make up the defect of easy cracking of the traditional marmite after being dried and burnt according to a certain proportion, and can not crack when being dried and burnt to more than 450 ℃ and put into water with the temperature of 20 ℃. Lithium in spodumene ore has higher chemical activity than potassium and sodium, and fluxing action than potassium and sodium, so that it can lower the sintering temperature of ceramic product. In the process requirements for preparing the heat-resistant porcelain at present, all spodumene used must be fully calcined before use, and although the calcined spodumene (i.e. clinker) can partially improve the ball milling efficiency and has better thermal stability, the calcination of spodumene needs energy consumption, time consumption, ceramic preparation process increase, environmental pollution increase and the like, and the technology is very important in how to use or not use the spodumene clinker as little as possible and directly use spodumene raw materials to replace the clinker.

The three examples and comparative examples were tested to obtain the following performance parameters:
wherein the thermal stability is carried out by adopting the method in GB/T3298-:
TABLE 1
As can be seen from Table 1, the thermal stability and the expansion coefficient of the heat-resistant porcelain produced in the example are equivalent to those of the comparative example, but the water absorption ratio of the comparative example is higher, which shows that the heat resistance produced by using spodumene raw material is not much different from the performance of the heat-resistant porcelain produced by using clinker, but the heat-resistant porcelain produced by using the process of the invention has no pores and lower water absorption ratio.
The heat-resistant porcelain is produced by the methods of example 3 and comparative example 1, and the production yield is counted, wherein the yield of example 3 is 98%, and the yield of comparative example 1 is 86%, which shows that the yield of the heat-resistant porcelain produced by using the spodumene green stock of the invention is obviously improved.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
