Description
Technical field
The present invention relates to glass, more particularly to a kind of pyroceram and preparation method thereof.
Background technology
Glass：A kind of transparent semisolid, semiliquid material, contiguous network structure is formed in melting, in cooling procedure
Viscosity gradually increases and hardened and non crystallized silicates nonmetallic materials.The composition of simple glass chemical oxide
(Na2OCaO6SiO2), main component is silica.It is widely used in building, for every wind printing opacity, belonging to mixing
Thing.Separately there are the oxide for being mixed into some metals or salt and show the coloured glass of color, and pass through specific process system
Safety glass obtained etc..Sometimes some transparent plastics (such as polymethyl methacrylate) are also referred to as lucite.
Glass is a kind of non-crystalline solids of random structure (from microcosmic, glass is also a kind of liquid), its molecule
There is the arrangement of long-range order unlike crystal in space, and be similar to liquid has shortrange order like that.Glass is as solid
Specific profile is equally kept, is flowed unlike liquid with Action of Gravity Field.
Glass state material is usually quickly to be cooled down by molten mass and obtained, cooled during from molten state to glassy transition
Viscosity increased dramatically in journey, and particle has little time to do regular arrangement and form crystal, does not disengage latent heat, therefore, glass
State material contains higher interior energy than crystalline state material, and its energy belongs to metastable state between molten state and crystalline state.From
Mechanics viewpoint sees that glass is a kind of unstable upper state, for example the trend of low-energy state conversion be present, that is, has crystallization to incline
To, so, glass is a kind of metastable solids material.
The primary raw material of glass production has glass former, glass adjustment thing and glass intermediate, and remaining is auxiliary material.
Primary raw material guides oxide, intermediate oxide and the network external oxidation thing that network is formed into glass；Auxiliary material includes clear
Clear agent, fluxing agent, opacifiers, colouring agent, decolorising agent, Oxidizing and Reducing Agents etc..
Traditional glass technology formula is simple, and without resistant to elevated temperatures function, service life is short, and application field is smaller.
