Abstract
A study has been made of the contact reaction of the most promising materials for electric-furnace construction (Al2O3, ZrO2, NbC, and boron carbonitride) with molybdenum and tungsten under conditions approximating to the operating conditions in industrial vacuum electric furnaces in the temperature range 1200–2400°C and pressures of 10−3 – 10−4mm Hg. The temperatures at which reaction begins have been determined, and the reaction of all the materials has been found to proceed more rapidly via the gas phase. The reaction between boron carbonitride and molybdenum and tungsten is shown to be accompanied by the formation of new phases on the metal surface.
