Preparation method of ceramic with mutton fat jade touch sense

Abstract

The invention belongs to the technical field of ceramics, and particularly discloses a preparation method of a ceramic with a mutton fat jade touch feeling , and the preparation method of the ceramic with the mutton fat jade touch feeling comprises the following steps: S1, preparing a green body layer; s2, preparing mutton fat jade glaze , and applying the mutton fat jade glaze to the green body layer, wherein the glazing amount is 150-300 g / m < 2 >; and S3, sintering for 60-100 minutes at the temperature of 1340-1355 DEG C, so as to obtain the ceramic with the mutton fat jade touch feeling . The mutton fat jade glaze is prepared from the following raw materials in parts by weight: 20-35 parts of kaolin, 10-20 parts of white frit, 10-16 parts of pyrophyllite, 6-12 parts of quartz sand, 6-12 parts of calcium oxide, 4-8 parts of wollastonite, 4-8 parts of a lubricant, 2-5 parts of a sintering aid and 1-3 parts of spodumene. The ceramic is oily, smooth and fine in touch feeling, has the touch feeling similar to that of mutton fat jade, and has good toughness.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a preparation method of ceramics with a touch of suet jade. Background technique [0002] Sheep fat jade, also known as suet white jade, as the name suggests is a jade like suet. The interpretation of modern gemologists is that high-quality Hetian jade white jade is white in color (may be slightly pale blue, milky yellow, etc.), with an oily, delicate and moist touch. [0003] CN111995382A discloses a preparation method of suet jade ceramic tile, which specifically discloses that the mineral composition of the suet jade protective glaze includes: in mass percentage, light-transmitting potassium feldspar: 35.0-45.0%, needle-shaped light-transmitting Kaolin 20.0~30.0%, fused silica 12.0~18.0%, corundum: 4.0~6.0%, barium carbonate: 6.0~8.0%, zinc oxide: 1.0~3.0%. The suet jade ceramic tile has a moist and delicate texture, and presents the matte luster of suet. During the continu...

In its formulation system, a large amount of feldspars and K 2 O, and K 2 O mainly exists in the liquid phase during the firing process, making it difficult to precipitate K 2 O-type crystals; moreover, K 2 O exists in the glass phase after cooling, and the existence of the glass phase is not conducive to the improvement of toughness and mechanical properties, resulting in insufficient toughness and mechanical properties
