Manufacturing method of transparent ceramic

TANAKA KEITA

The invention relates to a manufacturing method of bubble-defect-free transparent ceramic with high transmittance and uniform insertion loss in all in-plane areas. The method comprising the steps of: obtaining a candidate composition containing a binder, optionally a dispersant, and optionally a plasticizer; dissolving the candidate composition in a solvent, then reducing a contained solvent volume to 0.1% by mass or less, and measuring a glass transition temperature; selecting a candidate composition having a glass transition temperature of 25 C or more and 60 C or less as an organic additive composition; preparing the organic additive composition containing the binder, optionally the dispersant, and the plasticizer, and having the composition obtained in the selecting step; pulverizing a raw material for sintering formed from metal oxide powder and the organic additive composition to obtain a pulverized mixture; granulating the pulverized mixture; sintering the granulated mixture to obtain a sintered body; and pressurizing the sintered body.
