Molybdenum disilicide is gray square crystal powder. In MoSi2, molybdenum combine silicon by metallic bond and silicon combine silicon by covalent bond. It is stable at room temperature and pressure. Its specific resistance is 21.6*10-6. MoSi2 is insoluble in water and common mineral acids including aqua regia, but soluble in mixture acid of nitric acid and hydrofluoric acid. It owns excellent high temperature oxidation resistance, which can use as heating elements at high tempearature oxidizing atmosphere. Molybdenum powder is the raw material.
