Abstract

The invention discloses a green ceramic product and a production method thereof. The ceramic product comprises the following components in percentage by weight: 50 to 55% of SiO2, 8 to 11% of Al2O3, 3 to 5% of Fe2O3, 11 to 13% of CaO, 2 to 3% of MgO, 1 to 2% of K2O, 0.5 to 1% of Na2O, and the balance being water. The production method comprises the following steps: step a, pretreatment: subjecting the prepared raw materials to sunlight exposure and weathering to obtain china clay; step b, pulverizing and grinding the china clay; step c, mixing and stirring; step d, fermentation: wrapping china clay evenly mixed in the step c by a film to carry out fermentation; step e, shaping; step f, burning: calcinating semi-finished products in a kiln, after calcination, stopping heating, and naturally cooling semi-finished products in the kiln to obtain the green ceramic products. Prepared kaolin is taken as the raw material, no other ingredient is added, a special processing technology and burning technology are adopted to generate pit change, the generated product has glassy luster and natural glazing color; moreover, the manufacture cost is low, the product color is natural, and the natural characteristics of ceramic products can be maintained.

Description

technical field [0001] The invention relates to the technical field of porcelain manufacture, in particular to a green ceramic product and a production method thereof. Background technique [0002] Porcelain is made of porcelain stone, kaolin, quartz stone, mullite, etc., and the surface is covered with glass glaze or painted objects. Porcelain is formed by firing at a high temperature (about 1280°C~1400°C) in a kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to different temperatures. Sintered porcelain bodies generally contain less than 3% iron and are impermeable. Because of their relatively low cost and wear-resistant and impermeable properties, they are widely used by people all over the world. [0003] The predecessor of porcelain is the original celadon, which is the product of the transitional stage from pottery to porcelain. Celadon is a treasure of Han ceramic firing technology, as a kind of porcelain with cyan g...
