Embodiment 1
[0027] A black ceramic product and a production method thereof, the specific operation steps are:
[0028] a. Pretreatment: Prepare raw materials according to weight fraction, 82 parts of clay, including 1 / 3 of red mud, 0.7 / 3 of white mud and 1.3 / 3 of red mud, 24 parts of SiO2, 13 parts of Al2O3, 11 parts of Fe2O3, and 16 parts of CaO 5 parts, 5 parts of MgO, 5 parts of K2O, 2 parts of Na2O, 29 parts of Cu(OH), and 54 parts of water. The above-mentioned raw materials were exposed to the sun and weathered to obtain pottery clay;
[0029] b, crushing and grinding: open the box cover 3, place the annular 500-mesh screen 8, make it fit with the inner side wall of the box body 6, place the pottery clay in step a in the crushing box, bolt the box cover 3 and The box body 6 is locked, and the crushing knife 5 crushes the pottery clay in the crushing box. When the size of the sieve hole is 7, it is thrown out of the crushing box due to the centripetal force. The first motor drives the...

Abstract
The invention discloses a black ceramic product in the field. The black ceramic product is prepared from the following raw materials in parts by weight: 81 to 89 parts of clay, 23 to 26 parts of SiO2, 13 to 16 parts of Al2O3, 8 to 16 parts of Fe2O3, 16 to 17 parts of CaO, 4 to 9 parts of MgO, 4 to 9 parts of K2O, 2 to 3 parts of Na2O, 8 to 16 parts of Cu(OH)2 and 52 to 66 parts of water. The black ceramic product is uniform and pure in external color and is black from inside to outside.
Description
technical field [0001] The invention relates to the technical field of ceramics, in particular to a black ceramic product and a production method thereof. Background technique [0002] Black pottery, born in the Neolithic Age of China, is an ancient Chinese pottery technique. It has the reputation of being as black as lacquer, as loud as sound, as thin as paper, as bright as a mirror, and as hard as porcelain. Black pottery is black pottery made by carbon infiltration during the firing process. The production process of Chinese black pottery is more sophisticated, delicate, delicate and unique than the original painted pottery. As early as about 2,000 years before the production of porcelain, Chinese black pottery had reached a level of craftsmanship comparable to that of porcelain. [0003] General pottery clay contains a certain amount of iron oxide, manganeseoxide and other components, which will show different colors in different firing atmospheres. The atmosphere in t...
