The hafnium target material is formed into products through multiple steps such as raw material smelting-forging-rolling-heat treatment-machining-flaw detection-surface finishing-cleaning.
Hafnium can react with air to form an oxide film protective layer. When the temperature is 500 to 750°C, the oxide film will lose its protective effect and will combine with oxygen, nitrogen, and other gases when heated to form oxides and nitrides. When the temperature exceeds 800°C, hafnium will rapidly oxidize to form HfO2.
Hafnium has good corrosion resistance, it does not react with dilute hydrochloric acid, dilute sulfuric acid, and alkaline solutions, but is soluble in hydrofluoric acid and aqua regia.
