Beschreibung
Zusammenfassung:	A refractory container for evaporating metals, having significantly improved useful life and corrosion resistance properties, said container consists essentially of a refractory boride, boron nitride, and about 0.10 to 10 wt. % of a rare earth metal compound selected from one of an oxide, a nitride, a carbide, or mixtures thereof. Cette invention concerne un récipient réfractaire servant à l'évaporation des métaux et présentant des propriétés considérablement améliorées en terme de durée de vie et de résistance à la corrosion. Ce récipient est essentiellement composé d'un borure réfractaire, de nitrure de bore et d'environ 0,10 à 10 % en poids d'un composé métallique des terres rares choisi entre un oxyde, un nitrure, un carbure ou des mélanges de ceux-ci.
