Further, the lubricant is stearic acid and bonding agent PVA.
Further, the plasticizer uses the compound of phthalate.
A kind of processing method of high voltage withstanding aluminium oxide ceramics, includes the following steps：
A1：Profit weighs to obtain the part of each material of recorded constitutive material in claim 1 in the balance.
A2：Processing is crushed to aluminium oxide, silica and zircon sand, and carry out screening to make powder body material powder obtained
Body granularity is micro- following at 1 μm.
A3：Aluminium oxide is mixed with silica and zircon sand, sequentially added after mixing lubricant, binder and
Embryo material is made in plasticizer after mixing, then pass through the high-temperature calcination between 1000-1300.
A4:After the completion of firing, aluminium oxide dispensing has been molded, and is handled by finishing, completes entire aluminium oxide ceramics system
Make the Overall Steps processed.
Further, the finishing in the step A4 includes：It grinds, polish and carry out encapsulation process.
Further, in the step A3, aluminium oxide is mixed with silica and zircon sand, is added successively after mixing
Enter lubricant, binder and plasticizer, and the temperature in mixing is between 150-200 DEG C.
Compare the prior art, and the zircon sand and silica in the present invention can effectively improve the insulation in aluminium oxide
Performance, while the silicate in zircon sand can effectively improve the hardness of aluminium oxide ceramics, to reach the effect for resisting high voltage
Fruit, the case where avoiding overtension from puncturing aluminium oxide ceramics, occur.It is being heated simultaneously as binder using water-soluble paraffin
In the case of have good mobility.It is loose that powder after mist projection granulating must have good fluidity, density, flow angle friction temperature
Less than 30 DEG C.Grain composition is than conditions such as ideals, to obtain larger biscuit density.
