Dental alumina presintered body for forming highly translucent alumina sintered body
Provided is an alumina presintered body that forms an alumina sintered body that suppresses yellowing after sintering, has high light transmittance and high linear light transmittance even when sintered at atmospheric pressure, and has high aesthetics suitable for dental use. The present invention relates to a dental alumina pre-sintered body comprising alumina particles having an average primary particle diameter of 30-300 nm, a sintering aid, and a blue colorant, the content of the sintering aid being 10-5000 ppm.
本发明提供形成氧化铝烧结体的氧化铝预烧体,所述氧化铝烧结体抑制烧结后的黄变,即便是大气压下的烧结,烧结体也具有高透光性和高直线光透射率,具有适合于牙科用途的高审美性。本发明涉及牙科用氧化铝预烧体,其包含平均一次粒径为30~300nm的氧化铝粒子、烧结助剂和蓝色系着色剂,前述烧结助剂的含量为10~5000ppm。
