Abstract

The invention discloses a kind of preparation method of ceramic pan, wherein raw material weight number is：White 130 160 parts of titanium dioxide, 50 70 parts of silica, 10 15 parts of tungsten carbide, 5 10 parts of barium titanate, 58 parts of magnesium diboride, 35 parts of ceria, 35 parts of titanium dioxide, 58 parts of aluminum oxide, 12 parts of yittrium oxide, 12 parts of hafnium oxide, 5 10 parts of talcum powder, 46 parts of Chaohu sand, 5 15 parts of aluminium dihydrogen phosphate, 48 parts of steel fibre, 8 15 parts of carbon fiber, 10 15 parts of basic magnesium carbonate, 15 20 parts of microcrystalline glass powder, 40 55 parts of Ukraine's beeswax tcrude ore, 35 45 parts of hiddenite, 10 15 parts of lithium carbonate, 13 20 parts of aluminum nitrate.The present invention is white with titanium dioxide, silica, Ukraine's beeswax tcrude ore, hiddenite are major ingredient, greatly promote its hardness, and have anti-oxidation characteristics concurrently, it is aided with other each raw materials again, makes integral material that there is the characteristic of acidproof, alkaline-resisting, resistance to rapid heat cycle, each material complements each other, so that ceramic pan heat conduction is rapid, uniformly, be not in that bottom food is well-done and situation that top food is not well-done.

Description

A kind of preparation method of ceramic pan
Technical field
The present invention relates to ceramic technical field, and in particular to a kind of preparation method of ceramic pan.
Background technology
Chinese have just invented pottery early in about B.C. 8000-2000 (Neolithic Age).The device fired with clay Ware is pottery, and the vessel fired with china clay are porcelain.General name that is ceramic then being pottery and porcelain.Ancients' ceramics are referred to as bowl.It is every It is raw material with clay and china clay both clays of different nature, is made by technological processes such as dispensing, shaping, drying, roastings Implements can be ceramics.
Ceramics development history be Chinese civilization history an important part, China as four major acids ancient country it One, progress and development for human society are made that the contribution of brilliance, wherein the invention and development of ceramics are with more unique meaning Justice, each Chao Gedai has the ceramic of different artistic styles and different technical characteristics on Chinese history." china " in English The existing Chinese meaning, there is the meaning of ceramics again, clearly demonstrate that China is exactly " ceramic native place ".Grasped early in European Before porcelain manufacturing technology more than 1,000 years, Han nationality has just produced very exquisite ceramics.China is to apply pottery earliest in the world One of country, and Chinese porcelain enjoys the high praise of common people because of its high practicality and artistry.
With the development of modern science technology, occur many new ceramic kinds again in the last hundred years.They are not used Or the traditional ceramics raw material such as clay, feldspar, quartz is rarely employed, but other special materials are used, or even it is expanded to non-silicic acid Salt, the scope of non-oxidized substance, and there are many new techniques.Some national documents of US and European will " Ceramic " one word is interpreted as the common name of various inorganic non-metal solid materials.Therefore the implication of ceramics is actually much super More pass by narrow traditional concept.
People cook soup commonly using ceramic pan, and ceramic pan is adapted to carry out small fire stewing to food, boiled in a covered pot over a slow fire, stewed, and ceramic pan has Hardness is high, resistance to oxidation, non-corrosive, it is safe and non-toxic the advantages of, and ceramic pan heat conduction is rapid, uniformly.
Existing ceramic pan has the disadvantage that needs overcome：The pot of existing ceramic pan and sealing at pot cover are poor, cook Inner air and outer air flowing is big when preparing food, and along with existing ceramic pan conduction inequality is even, often occurs that bottom food is well-done and top is eaten The not well-done situation of thing, further, the heat impact strength of existing ceramic pan is poor, easily cracking.
The content of the invention
The defects of technical problems to be solved by the invention are to overcome prior art, it is further proposed that a kind of ceramic pan Preparation method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of preparation method of ceramic pan, comprises the following steps：
