Embodiment 1

[0027] The talc raw material is calcined at 1400°C to obtain calcined talc. The serpentine mineral powder (yellow-green antigorite) was leached with 1mol / L hydrochloric acid for 0.5 hours, and the filter residue was taken as serpentine waste. Weigh the raw materials according to the weight ratio: 45 parts of calcined talc, 35 parts of clay, 20 parts of feldspar and 5 parts of serpentine waste (calculated as dry product). Adding water to the raw materials, ball milling, sieving, iron removal, pressure filtration, aging, mud refining under reduced pressure, and molding to obtain a green body. The biscuit is put into the kiln for biscuit firing, the bisque firing temperature is 850-900°C, and the time is 3.5 hours; the fired biscuit is taken out and colored, and then glazed, and the glaze firing temperature is 1200-1280°C, and the time is 5 hours; After burning, keep it warm for 0.5 hours and then take it out. Serve. The obtained magnesia jade porcelain is light yellow-green, t...

Embodiment 2

[0029] The talc raw material is calcined at 1300°C to obtain calcined talc. The serpentine mineral powder (dark green lizardite) was leached with 2mol / L hydrochloric acid for 0.5 hours, and the filter residue was taken as serpentine waste. Weigh the raw materials according to the weight ratio: 50 parts of calcined talc, 30 parts of clay, 10 parts of feldspar and 8 parts of serpentine waste (calculated as dry product). Adding water to the raw materials, ball milling, sieving, iron removal, pressure filtration, aging, mud refining under reduced pressure, and molding to obtain a green body. The biscuit is put into the kiln for biscuit firing, the bisque firing temperature is 850-900°C, and the time is 3 hours; after taking out the fired biscuit, it is colored and then glazed, and the glaze firing temperature is 1200-1280°C, and the time is 6 hours; After burning, keep it warm for 0.5 hours and then take it out. Serve. The obtained magnesia jade porcelain is dark green, transpar...

Embodiment 3

[0031] The talc raw material is calcined at 1300°C to obtain calcined talc. The serpentine mineral powder (light yellow chrysotile) was leached with 1.5mol / L hydrochloric acid for 0.5 hours, and the filter residue was taken as serpentine waste. Raw materials were weighed according to weight ratio: 47 parts of calcined talc, 33 parts of clay, 15 parts of feldspar and 10 parts of serpentine waste (calculated as dry product). Adding water to the raw materials, ball milling, sieving, iron removal, pressure filtration, aging, mud refining under reduced pressure, and molding to obtain a green body. Put the biscuit into the kiln for biscuit firing, the bisque firing temperature is 850-900°C, and the time is 4 hours; after taking out the fired biscuit and coloring it, then glaze firing, the glaze firing temperature is 1200-1280°C, and the time is 5 hours; After burning, keep it warm for 0.5 hours and then take it out. Serve. The obtained magnesia jade porcelain is light yellow in co...

Abstract

The invention relates to a magnesium jade porcelain and a production method thereof. The blank of the magnesium jade porcelain comprises the following raw materials in parts by weight: 45-50 parts of calcninated talc, 30-35 parts of clay, 10-20 parts of feldspar, and 5-10 parts of serpentine waste (based on dry materials); the serpentine wastes is filter residue obtained after extracting serpentine mineral powder through inorganic acid. Due to use of serpentine waste, the production cost of the magnesium jade porcelain is lowered, the combination of the formula can ensure a high yield of the fired magnesium jade porcelain finished products and the cost is further lowered; the serpentine is of multiple colors and easy to dye, thus the prepared magnesium jade porcelain is colorful; serpentine has thermal insulation and heat preservation characteristics, so that the thermal insulation property of the magnesium jade porcelain is improved and the heat preservation effect is good. According to the method, the synergistic effect of all components in the formula can be fully played, the fired porcelain is high in yield, has many colors, good thermal insulation property, and is especially applicable to porcelain for cantering.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a magnesia jade porcelain and a production method thereof. Background technique [0002] Magnesia jade porcelain has the characteristics of high whiteness, good translucency, fine porcelain quality, and glossy glaze. It is a high-grade porcelain product in the field of Chinese and foreign ceramics, and it is currently recognized as an ideal porcelain for high-end hotels and restaurants. The main raw material of magnesia jade porcelain is talc, which has a flaky structure, which is easy to be oriented in the embryo body during the extrusion molding process, causing anisotropic repulsion of the embryo body, and causing shrinkage in different directions during the firing and cooling process. Uneven, so that the product produces greater stress, resulting in cracking of the product. Therefore, the firing of magnesia jade porcelain has the problems of difficulty in forming ...
