hafnium tetrafluoride(CAS: 13709-52-9)

Hafnium tetrafluoride (CAS: 13709-52-9) is a colorless to white crystalline solid with a molecular weight of approximately 171.93 g/mol. It is slightly soluble in water but readily soluble in non-aqueous solvents like organic solvents. Chemically, it is highly reactive with moisture and air, forming hafnium oxide and hydrofluoric acid. It has a low vapor pressure and is stable under normal conditions.

Hafnium tetrafluoride is typically synthesized by reacting hafnium(IV) oxide with hydrogen fluoride (HF). The reaction is carried out under anhydrous conditions to prevent hydrolysis. The process involves the conversion of hafnium(IV) oxide into hafnium tetrafluoride with high selectivity and yield, making it a reliable and efficient method for industrial production.

Hafnium tetrafluoride (CAS: 13709-52-9) is used in several industries, including electronics, where it is employed in the production of semiconductor materials and integrated circuits. It is also used in the chemical industry for catalysts and chemical precursors, and in the pharmaceutical industry for certain drug formulations and analysis.

Handling hafnium tetrafluoride (CAS: 13709-52-9) requires strict safety measures. It should be stored in a cool, dry environment away from sources of moisture and heat. Personal protective equipment (PPE) such as gloves, goggles, and a lab coat is essential. Work should be conducted in a well-ventilated area or a fume hood to prevent inhalation of dust and fumes. In case of a spill, it should be handled according to the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) guidelines, which includes the use of appropriate absorbent materials and disposal methods.
