Processing requirements and sintering procedures for zirconia plates

Update time : 2023-01-17 18:27:48

We should be familiar with zirconia plate, because it has its own characteristics: high temperature resistance, high strength, wear resistance, chemical stability and other characteristics, so that modern human widely used. So do you know the processing technology of zirconia plate? Do you know the sintering procedure of zirconia plate? Let's talk about the processing technology of zirconia plate and sintering procedure of zirconia plate.

Processing requirements of zirconia plate:

Contour polishing: This step depends on the process choose.
A. Pay attention to the distance of the needle per unit time, remember not to go too fast.

B. Timely change the needle

Thickness of the working support: the thickness of the support should be at least 0.7mm before sintering. Not less than 0.4mm after sintering.

Sintering: Before sintering, clean the debris on the support in time. After sintering, the size of the support has a 25% shrinkage space. Therefore, it is necessary to use a matching sintering furnace (1600 degrees Celsius).

Sintering procedure:

Starting room temperature

Heating rate: 7.99 degrees /min

End temperature: 1480 degrees Celsius

Hold time: 120min varies

Cooling rate: about 8 degrees /min (you can adjust yourself)

Opening: If the opening is about 300 degrees, it must be noted that there should be enough sintering working space during processing to prevent deformation. If necessary, it needs to be sintered as a whole. After sintering, each fulcrum is cut off before processing. After sintering, the material can achieve the required physical properties, such as close to the maximum strength of 1200mpa. At the same time, zirconia material has high strength. If fracture 1 is found, it is basically the problem occurred during the turning.

The above is the introduction of the processing requirements and sintering procedures of zirconia plate that we bring to you. I hope it will be helpful to you.
