Patent ID: 7816292

Claim:
A method of manufacturing a multi-component glass or glass ceramic powder in the form of nanoparticles, comprising: providing at least three initial glass forming materials; vaporizing all of the initial glass forming materials in a plasma to form vaporized components; and depositing the vaporized components on a substrate so that the vaporized components are organized in a vitreous state or in an amorphous form, which has a composition comprising 5 to 55 weight percent based on oxide of P 2 O 5 , 20 to 35 weight percent based on oxide of ZnO, and at least one initial glass forming material selected from the group consisting of 0.1 to 25 weight percent based on oxide of Na 2 O, 2.5 weight percent based on oxide of Li 2 O, 2 to 2.6 weight percent based on oxide of K 2 O, and 1 to 11.8 weight percent based on oxide of Al 2 O 3 .
