Some people worry about whether
zirconia is radioactive.
In fact, zircon derived from
zirconia requires multiple processing steps, such as purification and powder processing. This treatment will remove all impurities.
The standards of the State Food and Drug Administration have strict standards for all ceramic materials on the market, and they can only be used as medical materials after they meet the requirements of radiological experiments. Not only are there requirements for
zirconia, but also for decorative porcelain, alumina, glass ceramics, etc. Experiments show that the radioactivity of pure
zirconia powder is not only lower than glass ceramics, but even lower than human bone tissue.
