how to solve the sintering problem of zirconia ceramic bushing
First, the problem of unstable sintering shrinkage in zirconia ceramic bushing.
Sintering shrinkage is an important indicator of zirconia ceramic bushing.
Solution: Optimize powder properties and process parameters to improve sinter shrinkage stability in zirconia ceramic bushings.
Second, the problem of high porosity
Porosity is an important indicator affecting the mechanical properties and conductivity of zirconia ceramics. High porosity will lead to a decline in the mechanical properties and conductivity of zirconia ceramic products.
Solution: Reduce the gas in the powder and control the atmosphere during the sintering process to reduce the porosity in ceramic bushing.
The specific measures are as follows:
- Reasonable selection of powder: its purity and appropriate addition of additives should consider when selecting powder to improve its compactness, crucial for zirconia ceramic bushings.
- Strengthen atmosphere control: In the firing process of zirconia ceramics, the atmosphere must control to reduce gas residue and oxidation reactions.
Third, the problem of bubbles and cracks
Air bubbles and cracks are common problems in zirconia ceramic firing. Air bubbles and cracks can affect the mechanical properties and compactness of zirconia ceramics.
Solution: Increase oxygen oxidation and reduce thermal stress to reduce the generation of bubbles and cracks in zirconia ceramic.
In summary, common problems in the firing process of zirconia ceramics include unstable sintering shrinkage, high porosity, bubbles, and cracks. For zirconia ceramic bushing products, solutions should optimize according to the specific situation to improve the quality and performance of zirconia ceramic products. Follow us!
