As we all know, zirconia ceramic processing is a special ceramic with high hardness, brittleness and low fracture toughness. It has good high strength, hardness, high temperature resistance, acid and alkali corrosion resistance and high chemical stability. However, during the processing of zirconia ceramics, cracking sometimes occurs due to various reasons. So do you know how to solve the problem that zirconia ceramics always crack during processing? The editor below will introduce to you:

　　Solutions to the problem that zirconia ceramics always crack during processing: 

       1. The phenomenon of zirconia ceramics always cracking during processing is often closely related to the selection of raw materials, so we must start with ceramic raw materials. Ceramic raw materials must be strictly screened. .   

       2. When high-pressure grouting is used for zirconia ceramic processing, the inner cavity of the gypsum mold must be filled once during the grouting process. Do not add grout or do more than two groutings.   

       3. The demoulding timing of zirconia ceramic processing must be mastered well. When the poured product has a certain strength in the plaster mold, it can be demoulded. Be careful not to use force during the demoulding process. Handle it with care, pay special attention to the mold closing marks, and there should be no cracking. Once there is cracking, the zirconia ceramic will crack after it is porcelain.   

       4. The blank must be dried naturally in a cool and ventilated place to prevent excessive dryi
