Specific embodiment
In order to more clearly state the present invention, the present invention is further described with reference to specific embodiment.
The chemical property of lithium is active, and reduction density can be played by adding in micro lithium, and stronger solvent effect is presented, has
The advantages that reducing melting temperature and shortening firing period, the ability of lithium matter melt melting quartz is stronger in addition, and relatively low scope is just
The relatively low β type lithium aluminosilicate solid solutions of coefficient of thermal expansion can be generated, and lithium-containing compound crystal is precipitated, may be such that entire porcelain body
With smaller coefficient of thermal expansion.
Spodumene：Component content is：LiAl(SiO3)2Or Li2O·Al2O3·4SiO2, roast to 1000 DEG C or so Shi Xun
Speed is changed into β type spodumenes, reduces firing temperature, reduces melt melt viscosity, improves temperature flowing and vitreous degree, improves
Contamination resistance enhances glaze surface intensity and smooth degree；Coefficient of thermal expansion is reduced, overcomes glaze paint crackle, improves thermal stability；
Lithium glassy feldspar：It is a great deal of because having been received in melt lattice when it is precipitated from melt with very strong crystallization ability
SiO2So that the SiO to dissociate in melt2Content is reduced, thus cristobalite will not be because of SiO in melt2It is excessive and generate, it can be with
The volume expansion that quartz crystal Transition Zone comes is reduced, so as to reduce coefficient of thermal expansion；In addition petalite, which has, increases blank
The effect of plasticity and acceleration of sintering is strong.
Kaolin：Using distinctive plasticity itself, prevent the cracking situation in sintering procedure, compare it in addition
His material, kaolinic white are more suitable for colouring processing.
Quartz：By the mobility for changing glaze so that glaze is easier to be attached on blank, forms by a firing rear surface more
It is smooth.
Mullite crystalline substance alkene：It using the fire resistance of itself, is coated on material surface, improves the heat-resisting quantity of entire material.
Aluminium oxide：The opaque of glaze paint is improved, while there is fluxing action.
