Embodiment 1

[0027] Raw material preparation: In 100kg of raw materials, 35kg of bone meal, 20kg of kaolin, 16kg of lithium feldspar, 12kg of quartz, and 7kg of wollastonite are used; after the raw materials are beaten mechanically, they are passed through a 200-mesh sieve, and the screened raw materials are mixed and beaten for later use, and pressed into embryos; Then dry and bake at 500°C; place at 0-5°C for 1 hour after drying, and then glaze at room temperature; kiln and shape at 1100-1300°C.

Embodiment 2

[0029] Raw material preparation: 40 kg of bone meal, 25 kg of kaolin, 14 kg of lithium feldspar, 8 kg of quartz, and 13 kg of wollastonite are used in 100 kg of raw materials; after the raw materials are beaten mechanically, they are passed through a 200-mesh sieve, and the screened raw materials are mixed and beaten for later use, and pressed into embryos; Then dry and bake at 600°C; place at 0-5°C for 1 hour after drying, and then glaze at room temperature; kiln and shape at 1100-1300°C.

Embodiment 3

[0031] Raw material preparation: In 100kg of raw materials, 40kg of bone meal, 25kg of kaolin, 16kg of lithium feldspar, 12kg of quartz, and 17kg of wollastonite. After the raw materials are beaten mechanically, they pass through a 200-mesh sieve, and the screened raw materials are mixed and beaten for later use, and then pressed into embryos; then dried and baked at 550°C; after drying and baked, place them at 0-5°C for 2 hours, and then Put it at room temperature for glazing; kiln firing at 1100-1300°C for molding.

Abstract

A preparation method for bone-ash ceramic comprises the following steps: preparing raw materials, specifically performing mechanical beating on raw materials, sieving with a 200 mesh sieve for usage; performing mixing pulping on the prepared raw materials for usage; utilizing pressure to form a green body; drying at 500-600 DEG C; after drying is performed, placing at 0-5 DEG C for 1-2 h; glazing at normal temperature; and putting in a kiln and sintering for forming. According to the preparation technology, roasting for obtaining a green body can be finished at a relatively low temperature, and the prepared bone-ash ceramic has excellent heat stability, high qualified rate and low production cost.

Description

technical field [0001] The invention relates to the field of ceramic preparation, in particular to a method for preparing bone ash ceramics. Background technique [0002] Bone China is a kind of porcelain made from animal ashes or synthetic bone meal, clay, feldspar and quartz sand, which are fired twice by high-temperature biscuit firing and low-temperature glaze firing. Bone china is fine in quality, high in whiteness, good in translucency, regular in vessel and bright in picture. It is widely used in the production of high-grade daily-use porcelain and high-grade display art porcelain. Double value, known as the king of porcelain. [0003] At present, after the embryo body of bone ash china is formed, it is bisque fired at about 1300°C, then glazed, and then glazed and fired at high temperature; due to two high-temperature firing processes, especially in the first bisque firing During the process, carbonization or local damage is prone to occur due to problems such as r...
