Abstract
The invention discloses a preparation method of a heat-resistant ceramic. The preparation method comprises the following steps: (1) weighing raw materials according to parts by weight; (2) placing the raw materials into a ball mill for grinding, and sieving to obtain a mixed material with the mesh number of 80-120; (3) adding water to prepare pulp; (4) after uniformly stirring, filtering and removing sediments to obtain a blank material; (5) placing the blank material into a reaction furnace with the temperature of 1500-1800 DEG C to heat for 24-48h for the first time, after preserving the heat for 20-50min, reheating at the temperature of 900-1200 DEG C for 5-10h, and naturally cooling to obtain the ceramic material. A reasonable formula is adopted in the preparation method of the heat-resistant ceramic, disclosed by the invention; through controlling the particle sizes of the materials and processing flows, the heat resistance of the heat-resistant ceramic is up to over 900 DEG C, and the thermal shock resistance of the heat-resistant ceramic is enhanced; in addition, no lead-contained raw materials are adopted in the raw materials, so that the environment friendliness of the ceramic is ensured.
Description
Technical field
The present invention relates to impregnating material field, particularly relate to a kind of preparation method of heat-stable ceramic.
Background technology
Pottery is widely used in life or production very early, but with regard to current ceramic performance, its thermotolerance and thermal-shock resistance are all poor.The temperature that conventional ceramic bears is 400-600 DEG C, so often there is china bowl or porcelain cup cracking phenomena.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of preparation method of heat-stable ceramic.
For solving prior art problem, the technical scheme that the present invention takes is: a kind of preparation method of heat-stable ceramic, comprises the following steps:
(1) following raw material is taken according to parts by weight: trichroite 15-30 part, quartzy 10-15 part, barium oxide 1-3 part, silica 1 5-20 part, terbium sesquioxide 1-3 part, aluminum oxide 15-30 part, clay 1-3 part;
(2) above-mentioned raw materials is dropped in ball mill grind the 80-120 order compound that sieves to obtain;
(3) add water slurrying, and Mass Control percentage ratio is at 9-11%;
(4) cross elimination after stirring and precipitate to obtain blank material;
(5) blank material being put into temperature is that the Reaktionsofen of 1500-1800 DEG C heats 24-48 hour first, and be incubated after 20-50 minute, again heat 5-10 hour, temperature is 900-1200 DEG C, after naturally cooling stupalith.
Preferably, described compound order number is 120 orders.
Preferably, the Heating temperature first of described step (5) is 1600 DEG C, heats 40 hours.
Beneficial effect: the preparation method of a kind of heat-stable ceramic of the present invention adopts composition of reasonably filling a prescription, control the granular size of material, and the program of processing, its resistance toheat is made to reach more than 900 DEG C, thermal shock resistance strengthens, do not adopt raw material containing lead in raw material in addition, ensure that the environmental protection of pottery.
