POLYMER COMPOSITION FOR PRODUCING NIOBIUM AND TANTALUM CARBIDES AND SOLID SOLUTIONS THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: polymer composition includes a compound of a refractory and a carbon carrier in the form of phenol-formaldehyde binder, taken in a stoichiometric ratio, and a lubricant. The refractory metal compound used is separate or bimetallic niobium and/or tantalum hydroxide.;EFFECT: disclosed composition enables to obtain single-phase niobium and tantalum carbides and solid solutions thereof in the form powders or porous articles with low-temperature synthesis.;5 ex, 1 tbl
