POLYMER COMPOSITION Russian patent published in 1996 - IPC

FIELD: preparation of metal carbides. SUBSTANCE: polymer composition for preparing high-purity monocarbides of high-melting metals and articles therefrom is characterized by high technological effectiveness and availability of starting materials. It provides completion of carbidization reaction in whole volume of preliminarily shaped article and uniformity in its chemical structure. Composition has (in wt %): high-melting metal oxide 12.0-28.3, phenol binder 4.3-15.1, zinc stearate 1.0-2.2, and high-melting metal carbide 54.8-82.7. EFFECT: enabled fabricating low-porous carbide articles, for instance, targets for magnetron spraying. 2 tbl
