Description

General description

Molybdenum disilicide exhibits thermal stability, excellent oxidation resistance, and good electrical conductivity. The high melting point of 1870-2030 °C suggests it can withstand extremely high temperatures without undergoing phase changes ordegradation. Owing to its exceptional properties it is widely explored in the field of heating elements, furnaces,and aerospace components. High purity of ≥99% trace metals basis facilitates its use in electrode materials for Lithium oxide batteries. It is also utilized as an efficient cocatalyst for solar hydrogen production.
