Embodiment

[0016] In the preparation method of the daily-use ceramics in this embodiment, the raw material formula of the daily-use ceramics is: 45% kaolin, 20% quartz, 10% potassium feldspar, 20% alumina, 4.3% zinc oxide, and 0.7% ceria.

[0017] The specific steps of the daily ceramic preparation method are:

[0018] 1. Preparation of raw materials: select, coarsely crush and weigh quartz, kaolin, potassium feldspar, etc. respectively;

[0019] 2. Making finished mud: mixing, coarse grinding, 120-mesh sieving, pulping, wet ball milling, sieving, pressure filtration, rough refining, stale, and refining of the raw materials weighed in step 1 to make finished mud;

[0020] 3. Forming: use conventional forming methods to form;

[0021] 4. Firing: Load the formed products into blanks, fire at 1350 ℃, open the porcelain, and select qualified fired products.

Abstract

The invention provides a preparation method for daily-use ceramic. The raw material formula comprises, by weight, 40-45% of kaolin, 15-25% of quartz, 10-15% of potash feldspar, 10-20% of alumina, 4-6% of zinc oxide and 0.6-0.8% of cerium dioxide. The daily-use ceramic integrates characteristics of high strength and high weight, and also has the advantages of good molding performance, wide sintering scope, high thermal stability and the like; the glossiness of ceramic glaze is improved, glaze is smooth, and the ceramic has good hardness, rupture strength and fracture toughness; the disadvantage of bad light transmittance of common strengthen porcelain is overcome, and also the problems of difficult molding and narrow sintering scope are solved.

Description

technical field [0001] The invention belongs to ceramic technology, in particular to a preparation method of daily-use ceramics. Background technique [0002] my country has a history of ceramic culture for thousands of years. In the existing ceramic preparation technology, ordinary daily-use ceramics can only be prepared from ordinary raw materials, which are fired once. However, high-grade daily-use ceramics are fired twice. It is a world-recognized high-grade porcelain. In the prior art, it is still impossible to prepare high-grade products by adopting the general one-step sintering technology. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a preparation method of daily-use ceramics, so as to produce high-grade daily-use ceramics whose performance parameters are no less than that of bone china. [0004] The preparation method of daily-use ceramics provided...
