摘要: A method for producing a metal fluoride ceramic, comprising: providing a sedimented compound comprising metal fluoride particles having an average particle size lower than 30 nm and a solvent, partially drying the sedimented compound at a temperature lower than 65°C until the partially dried compound comprises from 5 wt% to 45 wt% of the solvent, and sintering, for example in air, the partially dried and sedimented compound. The resulting ceramic is a transparent metal fluoride ceramic having an average grain size lower than 450 nm and having an absorbance lower than 0.05 cm -1 at 1200 nm and lower than 1 cm -1 at 370 nm. Preferably calcium fluoride is used.
