Description
Involved in the present invention is a kind of glass material and manufacture method thereof.Particularly relate to a kind of goose cord rock of using
*Low-expansion glass-ceramic and the technology thereof made.
Low-expansion glass-ceramic has splendid cold-resistant hot acute degeneration, and high physical strength and hardness and good saturating microwave property are a kind of glass materials that using value is arranged very much.In modern industry and daily life, its application surface is quite extensive, be mainly used in and make heat-resisting devitrified glass vessel, microwave oven utensil, microwave oven and electromagnetic stove plate, and other industrial low bulk high hardness material such as devitrified glass jewel and infrared radiant material etc.
Known low-expansion glass-ceramic all uses industrial chemicals production.((1) S.D.Stookey, " Method of Making Ceramics and Product Thereof; " U.S.Patent 2,920,97) (January 12,1960) S.D.Stookey .(2), " Low-Expansion Glass-Ceramic and Method of Making It ", U.S.Patent3,157,522.(November G.P.Smith 17,1964) .(3), " Method of Making Ceramic Atticle " U.S.Patent 3,246,972, (Aptil 19,1966) .) it is by Li

2O(K
2O), MgO, in high-temperature smelting pot, be melt into uniform glass liquid, make devitrified glass through crystallization control again after the moulding.Because its used expensive raw material price up to 1.8 ten thousand yuan/ton, has limited its development as the industrial chemicals Quilonum Retard.Moreover, for Li
2O content be about 4% glass melting temperature up to 1600 ℃ about, energy consumption is big in the production, brings a series of problems also for simultaneously furnace refractories and molding device.Thereby, how to reduce cost and temperature of fusion has become the problem that presses for solution in the low-expansion glass-ceramic production.
In general, be applicable to that the raw mineral materials of making low-expansion glass-ceramic is except that should containing Lithium Oxide 98min, aluminum oxide and silicon-dioxide, the content of its detrimental impurity-potassium, na oxide and iron should lack, the former too high levels will cause the increase of devitrified glass thermal expansivity, and ferric oxide surpasses the whiteness that allowance (as greater than 0.06%) can seriously influence product.In fact, the raw mineral materials that can satisfy above-mentioned two conditions is few for number on earth, reason that low-expansion glass-ceramic still produces with industrial chemicals so far that Here it is.
The object of the present invention is to provide novel method and the goods thereof of making low-expansion glass-ceramic with goose cord rock.Goose cord rock is newfound a kind of
* the place of production: near volcanic rock Tongan City, Yifeng County, Jiangxi Province, can reduce devitrified glass cost and temperature of fusion with it significantly as the main raw material of manufacturing low-expansion glass-ceramic.
The method of manufacturing low-expansion glass-ceramic of the present invention mainly comprises following content:
