Clay raw materials are also called plastic raw materials. Commonly used plastic raw materials include: kaolin, wood knot soil, china clay, bentonite, etc. Quartz is a non-plastic raw material, and feldspar is a solvent raw material. In addition to feldspar, solvent raw materials also include nepheline syenite, Granite, lithium-containing minerals, pumice and other feldspar substitutes, calcium carbonate of calcite, limestone, chalk, marble, magnesium carbonate of magnesite and bitter soil, magnesium silicate of dolomite, talc, serpentine In the calculation of ingredients, the proportion of feldspar, quartz, etc. is determined according to the chemical composition of the clay. Due to the scarcity of jade reserves and the high price, jade is used as a raw material for ceramics. not in technology

Embodiment 1
[0010] A kind of pottery that adds jade powder, take clay, feldspar, quartz as base material, add jade powder into the base material, the grain size of jade powder is 800~1000 mesh, its composition is (weight percentage): clay 30%, 25% feldspar, 25% quartz, 20% jade powder, and then add an appropriate amount of water.
[0011] The above ingredients are uniformly mixed, blanked, drawn, molded, dried for 6 hours, and fired at a high temperature of 1100°C for products or test pieces.
[0012] After the above-mentioned firing, the appearance whiteness of the test piece increases by ≮75, the transparency (1mm thickness)>3, the Mohs hardness, compressive strength, and tensile strength are all greatly increased, and it is not easy to break.

Abstract
The present invention relates to a kind of ceramics to which the jade powder is added, which is characterized by that it uses clay, feldspar and quartz as base material or uses talcum, feldspar, kaolin, magnesium oxide and silicon oxide as base material or uses kaolin, quartzite, feldspar and phosphate as base material and adds the jade powder to said base material, and its composition comprises (wt%) 70-90% of base material and 10-30% of jade powder. The whiteness of the product made up by said method is increased, and its Mohs' hardness, compression strength and tensile strength are greatly raised.
Description
technical field [0001] The invention relates to a ceramic, especially a ceramic added with jade powder. Background technique [0002] The traditional ceramic material is feldspar porcelain with clay, feldspar and quartz as the solvent, which is a typical representative of porcelain. In addition, there are talc, feldspar, kaolin and other magnesium oxide and silicon oxide components. Talc porcelain, bone porcelain composed of kaolin, quartz stone, feldspar, phosphate and so on. Clay raw materials are also called plastic raw materials. Commonly used plastic raw materials include: kaolin, wood knot soil, china clay, bentonite, etc. Quartz is a non-plastic raw material, and feldspar is a solvent raw material. In addition to feldspar, solvent raw materials also include nepheline syenite, Granite, lithium-containing minerals, pumice and other feldspar substitutes, calcium carbonate of calcite, limestone, chalk, marble, magnesium carbonate of magnesite and bitter soil, magnesium s...
