HAFNIUM(IV) CHLORIDE - Introduction
Hafnium(IV) chloride is the chloride of Hafnium with the chemical formula hfcl4. The following is a description of the nature, use, formulation and safety information of Hafnium(IV) chloride:
Nature:
- Hafnium(IV) chloride is a colorless liquid that produces white crystals at room temperature.
-Has a strong pungent odor.
-Under the condition of sufficient moisture in the air, it will react with water to form hafnium hydroxide and hydrochloric acid.
- Hafnium(IV) chloride is a strong acidic compound with strong oxidizing and corrosive properties.
-Soluble in anhydrous ether and carbon tetrachloride, insoluble in most organic solvents.
Use:
- Hafnium(IV) chloride is commonly used as a catalyst in organic synthesis.
-Used to prepare hafnium oxide, perovskite thin films and coating materials.
-Used in the semiconductor industry to manufacture specific types of transistors and integrated circuits.
-For the preparation of high purity metal hafnium and other hafnium compounds.
Method:
- Hafnium(IV) chloride can be prepared by reacting metal Hafnium with chlorine gas. The specific method is to heat the metal Hafnium to above 800 ℃, and then use chlorine gas to flow into the reactor to form Hafnium(IV) chloride.
Safety Information:
- Hafnium(IV) chloride is irritating and corrosive. When in contact with skin and eyes, rinse immediately with plenty of water.
-Avoid inhaling gas or vapor during use, and operate in a well-ventilated place.
-Keep away from flammable materials and oxidants when stored, keep sealed, and avoid contact with water.
-If ingested or inhaled, seek medical attention immediately.
