Vacuum Induction Furnace Melting Technology for High-Temperature Composite Material Based on Nb–Si System

详细

FGUP VIAM has developed technology for melting high-temperature composite material based on the Nb–Si system by vacuum induction melting in a ceramic crucible based on yttrium oxide operating at a melting temperature of more than 2000°C and chemically resistant during melting a highly active composite. This technology makes it possible to prepare billets for directional crystallization of the required geometric dimensions, ensuring a homogeneous chemical composition close to that calculated, and a low impurity content, in particular oxygen.
