Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] The chemical composition of the raw materials used in the examples is shown in Table 1, the composition of the body is shown in Table 2, and the biscuit firing temperature range is 1300-1330°C.

[0024] Among them, the crystal stone is pretreated, first calcined at a temperature of 1250-1300 ° C, and then at a weight concentration of 15-20%, such as 15%, 16%, 16.5%, 17%, 17.5%, 18%, 19% or Soak in 20% hydrochloric acid solution for pickling, rinse with water until neutral after pickling, and then grind separately and control the particle size distribution to 5-20 μm. In the bisque firing process, in the temperature range of 500-600°C and 850-950°C, slow heating and cooling are required. The heating rate of slow heating is 10°C / 10 minutes, and the cooling rate of slow cooling is 15°C / 10 minutes.

[0025] The same glaze is applied to the bodies of all the examples, and the glaz...

Abstract

The invention relates to a crystal ceramic which is a new product of ceramic products, or a new ceramic type. Glaze is coated on a green body which is prepared from the following components by weightpercent: 75-82 percent of SiO2, 15-21 percent of Al2O3, 0-0.1 percent of Fe2O3, 0-0.1 percent of TiO2, 0-0.5 percent of CaO, 0-0.9 percent of MgO, 0.5-2.6 percent of KNaO, 0.1-0.8 percent of Li2O and0.1-0.5 percent of BaO. The invention has the characteristics of wide range of firing temperature, easy firing control, high whiteness, favorable translucency, high mechanical strength and favorable thermal stability. The invention also provides a preparation method comprising the steps of preparing materials, dosing, molding, biscuiting, enamelling and glaze firing, wherein the crystal needs to be preprocessed, and the preprocessing comprises the steps of calcining at 1250-1300 DEG C, washing with acid, washing with water to neutrality and separately grinding and controlling the grain diameter ranges from 5 to 20 microns. The invention is scientific and reliable, is easy to implement and ensures the quality and qualification rate of products.

Description

technical field [0001] The invention relates to a crystal porcelain, which is a new type of ceramic product, or a new type of porcelain. Background technique [0002] Among ceramic products, there are high-grade porcelains such as feldspar porcelain, steatite porcelain, quartz porcelain, bone china, etc. The existing high-grade porcelain generally has the problems of small firing temperature range, difficult firing control, and it is difficult to have high whiteness at the same time. , Good translucency, high mechanical strength and good thermal stability. Contents of the invention [0003] The object of the present invention is to provide a kind of crystal porcelain, which has a wide firing temperature range, easy firing control, and has the characteristics of high whiteness, good translucency, high mechanical strength and good thermal stability; the present invention also provides The preparation method is scientific and reasonable, easy to implement, and ensures produc...
