Regarding the phenomenon of cracking after sintering alumina ceramics, please analyze the reasons

Is the landlord's tunnel kiln in the north or south?The temperature is reduced, and the body molding is prone to slight cracks.
The speed of the car is too fast, and the kiln furniture has uneven heat transfer and it is prone to problems.

First find a batch of cracks inside, if so, find different.
If not, it is recommended to do it as follows:
Mainly observe how the so -called large cracks and hair cracks are different, such as placing positions, raw materials and molding processes (batch), and the position of cracks appear.EssenceFind the problem first to apply the right medicine.

It is mainly caused by cracks when forming. If you want to avoid, after the powder is formed, carefully observe whether the body has fine cracks, require better eyesight, and then pick out the intact body.

It feels that the landlord has a crack after sintering at the high temperature kiln. It should be a problem that occurs when the semi -finished product is suppressed. It may be caused by uneven pressure everywhere when suppression.In the past, the titanium dioxide was suppressed, although the pressure was uneven, although the semi -finished tablet was no problem, but cracks will appear after 1000 degrees sintering
