Performance is recorded into the following table 3.
Table 3
Show that mullite and cordierite are added in ceramic raw material can be improved the flexural strength of product by the above test result
And its coefficient of expansion is reduced, in order to guarantee that it is sufficiently sintered, need to use lithium porcelain stone as strong flux.In this series embodiment
Middle firing temperature is 1195 DEG C, and firing period is 65 minutes.According to the chemical constituent ratio range of raw material, counted referring to Sai Geershi
The sintering temperature of calculation, it is 1100 DEG C~1250 DEG C that this series, which matches suitable sintering temperature, and firing period is 40~180 minutes
(firing period is specifically determined according to the design of kiln).
Lithium porcelain stone is the strong flux for being suitble to this formula system, wherein the lithium contained can generate liquid at a lower temperature
Phase, acceleration of sintering, and it can make the fluctuation range of the coefficient of expansion smaller, and the coefficient of expansion (100~400 DEG C) is basically stable at
100~120 × 10-7/℃.This is because lithium, sodium, the content ratio of potassium are suitable in the chemical component of lithium porcelain stone, in sintering process
In, the liquid phase for melting formation first can make cordierite and mullite particle blend to form firm solid solution with other objects very well
Body, and there is certain elasticity, and then intensity is high, the coefficient of expansion is small, has good impact resistance.The porcelain plate that this technique obtains
Material can be applied to the occasions such as hearth table top, cabinet body cover.
By testing proportion above it is found that it is 8%~10% to be advisable that the dosage of mullite is calculated by mass percentage, cordierite
Dosage is calculated by mass percentage to be advisable for 12%~18%, and the dosage of lithium porcelain stone is calculated by mass percentage to be advisable for 1%~3%.
Mullite is high refractoriness object phase with cordierite, and under architectural pottery firing temperature system, and mullite and cordierite are very
Difficult fusion and decomposition, the melting liquid phase for mutually relying primarily on flux generation with other objects are merged, therefore when dosage is excessive, are needed
Firing temperature is improved, extends firing period to ensure that product is sufficiently sintered, it is therefore desirable to be used in suitable ratio range.This
Outside, after high-temperature fusion, other object phases may be will form or become amorphous state, not have corresponding characteristic thus, therefore burn
Junction temperature is advisable with 1200 DEG C or less.The dosage of lithium porcelain stone as strong flux be also required to it is matching, in this way melt after produce
Raw solid solution, which combines, to be stablized, and ceramic sheet flexural strength is big.

88MPa, this has also confirmed mullite occurs mostly in the form of primary mullite in architectural pottery, and acicular mullite crystal whisker can
It to be dispersed in powder, is also uniformly dispersed in adobe after punch forming, during high temperature firing, strong flux lithium porcelain stone melts
Acicular mullite is wrapped up or is entered in the gap of its accumulation by the liquid phase after change, is also after the melting of the flux such as subsequent mountain flour, talcum
So.And the partial size of mullite and cordierite preferably≤325 mesh, mesh number indicate an area in square inches on possessed mesh
Number, the bigger expression partial size of numerical value is smaller, means that particle can pass through the sieve of this mesh number completely less than or equal to some mesh number
Net, noresidue.
