Abstract

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.
