Abstract
The production process of semitransparent nucleated inorganic ceramic material, comprises the following steps: uniformly mixing silicon dioxide, aluminium oxide, boron oxide, potassium oxide and fluoride as raw material, melting in crucible, precooling, blowing, extruding and drawing or casting to btain glass solid bodies or cavity products with various forms, such as flower vase, said invented product is semitransparent, can be compared favourably with natural jade, can implement large-scale production.
Description
The present invention relates to inorganic ceramic material and production technique thereof, particularly a kind of translucent microcrystal inorganic ceramic material and production technique thereof.
At present, processing to machinable glass ceramic, require necessary porcelain degree very high, otherwise be difficult to processing, and the transparency of glass-ceramic is very poor, seem not attractive in appearance, in addition, natural jade as make a present and family adornment widely accepted, though but natural jade seems very luxurious, transparent feel is also arranged, but all very difficult, not only resource-constrained to the collection of natural jade and processing, and can only carve by hand, can not cast or blow, thus can not be processed into arbitrary shape, and time-consuming.
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of translucent microcrystal inorganic ceramic material and production technique thereof are proposed, this stupalith not only can be processed into the entity of different shape on lathe, and can cast, and can be blow molded into the cavity goods of different shape, as vase etc., the finished product that this material is made has translucent sense, can match in excellence or beauty with natural jade, the gentle exquisiteness of feel, pore-free, and can be mass-produced, and raw materials for production and finished product are nontoxic, compliance with environmental protection requirements.
For achieving the above object, solution of the present invention is: getting with silicon-dioxide, aluminium sesquioxide, boron oxide, potassium oxide, fluorochemical is that each is an amount of for main raw material, with being positioned over precooling after the fusion in acidic oxide or the platinum crucible after its mixing, blow, cast, push or be drawn into glasswork then.
Production process of the present invention is: the weight ratio of getting following raw material is: silicon-dioxide 35-60%, aluminium sesquioxide 5-20%, boron oxide 5-10%, magnesium oxide 0-10%, zinc oxide 0-10%, Lithium Oxide 98min 0-8%, sodium oxide 0-6%, potassium oxide 0-9%, calcium oxide 0-8%, fluorine 5-10%, tinting material are an amount of, preparation technology is: be positioned in acidic oxide or the platinum crucible after at first above-mentioned raw materials being mixed, temperature remains on 1300-1400 ℃, places to begin to stir, reach no bubble after making its complete fusion in 1.5-15 hour; Precipitation 1-4 hour in stove then, be chilled to 1100-1200 ℃ in advance after, become the glass entity or the cavity goods of definite shape through routine blowing, extruding, drawing or casting technique; Secondly, it is to take out after 650-850 ℃ stove is incubated 0.1-10 hour that the vitreum goods are put into temperature, the vitreum goods is put into temperature again and is 500 ℃ stove slow cooling and take out after 3-8 hour; At last, the goods that make are formal finished product through mechanical grinding or etch polishing.
The inorganic ceramic material goods that go out through above prepared contain silicon-dioxide 35-60%, aluminium sesquioxide 5-20%, boron oxide 5-10%, magnesium oxide 0-10%, zinc oxide 0-10%, Lithium Oxide 98min 0-8%, sodium oxide 0-6%, potassium oxide 0-9%, calcium oxide 0-8%, fluorine 5-10%, tinting material is an amount of.
Embodiments of the invention 1 are to make entity class goods prescription and technological process: the weight ratio of getting following raw material is: silicon-dioxide 50%, aluminium sesquioxide 15%, boron oxide 5%, magnesium oxide 10%, potassium oxide 9%, calcium oxide 1%, fluorine 10%, tinting material are an amount of, at first pour in the crucible that is heated to 1350 ℃ through batch mixing and be incubated 2 hours, use Al after the fusion by above-mentioned prescription
2O
3Rod or metal bar stir, and redeposition is chilled to 1200 ℃ in advance after 1.0 hours, then through being cast as the glass physical article of certain shape; Secondly, the glass physical article being placed in 500 ℃ of annealing furnaces slow cooling took out after 4 hours; Furnace cooling or 1 hour furnace cooling of 500 ℃ of isothermals are to room temperature, after mechanical grinding is finished product after the glass physical article being placed 650 ℃ of stoves to be incubated 4 hours again.
It is an amount of that the inorganic ceramic material goods that go out through above prepared contain silicon-dioxide 50%, aluminium sesquioxide 15%, boron oxide 5%, magnesium oxide 10%, potassium oxide 9%, calcium oxide 1%, fluorine 10%, tinting material.
