What factors are related to the light transmittance and strength of zirconia on the material?
Generally speaking, the transparency of zirconia has an inverse relationship with its strength. The better the transmittance of zirconia, the lower the strength.
1. Alumina has a certain toughening effect in zirconia, but the higher the alumina content, the greater the impact on transparency. The high content of alumina has good mechanical properties, but the transparency is greatly reduced.
2. The content of stabilizer yttrium oxide is also related to the transparency and strength of zirconia.
3. The particle size and agglomeration size of zirconia powder are also related to transparency and strength.
