TLDR
In this paper, a method of making a laser body from a high density yttria-based ceramic material is provided, which involves forming an aqueous solution containing water soluble salts of yttrium, thorium, and neodymium, coprecipitating the cations from solution with oxalic acid, recovering the oxalate precipitate in the form of a purified dried powder, calcining the powder to convert oxalates to oxides, particulating the oxides in a rubber-lined ball mill, pressing the powdered oxides into aAbstract:
A method of making a laser body from a high density yttria-based ceramic material is provided. The method involves forming an aqueous solution containing water soluble salts of yttrium, thorium and neodymium, coprecipitating the cations from solution with oxalic acid, recovering the oxalate precipitate in the form of a purified dried powder, calcining the powder to convert the oxalates to the oxides, particulating the oxides in a rubber-lined ball mill, pressing the powdered oxides into a "green body", sintering the "green body" in a hydrogen atmosphere and rapidly cooling the sintered body to form an improved lasing ceramic material.read more
