Is Dental Zirconia Ceramic Blank Safe?

 Zirconia ceramic blank applied in dentistry and medical performs great at biosecurity. Long time ,lots of experiment and clinic cases proved that zirconia ceramic blank doesn't have toxicity to bone and soft tissue cell.

Does zirconium ceramic blank have radioactivity?

In fact,  zircon for making zirconium ceramic blank is purified. During the process, its all impurity are removed.

CFDA controls all ceramics material on market very strictly. Only qualified zirconium accordance with radioactivity experiment requirement can be used as medical material. Experiment proved that zirconium powder radioactivity even lower than human beings bone tissue.
