Description

A kind of aluminium oxide ceramics gas kitchen range panel preparation technology
Technical field
The invention belongs to casting technology field, and in particular to a kind of aluminium oxide ceramics gas kitchen range panel preparation technology.
Background technology
At present, aluminium oxide ceramic products are typically prepared by 96% aluminum oxide, but its bending strength only has 300MPa or so, the aluminium oxide ceramics of the intensity easy forced breakage during assembling process and use, directly affects panel Service life, so research one new alumina ceramic panel preparation technology it is most important.
The content of the invention
In order to overcome above-mentioned technical problem existing for prior art, it is an object of the present invention to provide one kind to aoxidize Aluminium ceramic gas range panel preparation technology, the aluminium oxide ceramics with very strong anti-crushing ability can be prepared.
A kind of aluminium oxide ceramics gas kitchen range panel preparation technology provided by the invention, comprises the following steps：
1）Component is weighed according to following weight/mass percentage composition：85%~95% alumina powder, 2%~6% titanium dioxide powder, 2.5%~8% magnesia powder and 0.5%~1.5% nano-ceramic powder, nano-ceramic powder are chromium oxide powder or nitridation Silica flour；
2）Alumina powder, titanium dioxide powder, magnesia powder and nano-ceramic powder are mixed, obtain green powder；
3）Slurry is spontaneously dried 10~12 hours；
4）In 50~60 DEG C of oven dryings 12~15 hours；
5）Green powder is loaded into mould, aluminium oxide ceramics is obtained after pulse electric current sintering.
A kind of aluminium oxide ceramics gas kitchen range panel preparation technology provided by the invention, its advantage be, by using Titanium dioxide powder and magnesia powder are doped modification to alumina powder, and titanium dioxide and magnesia can be in the form of glass phases The grain boundaries of aluminium oxide ceramics are distributed in, so as to greatly strengthen the slidability between alumina grain, so that material shows Go out higher fracture toughness so that the anti-bending strength of aluminium oxide ceramics significantly improves, and security is more preferably.
