The use of hafnium tetrachloride mainly includes the following aspects:
1. Semiconductor field:
• Precursor materials: In the semiconductor industry, hafnium tetrachloride is used in chemical vapor deposition (CVD) and atomic layer deposition (ALD) techniques to deposit hafnium oxide (HfO₂) films.Hafnium oxide has a high dielectric constant and is an ideal gate insulator material in field-effect transistors, helping to improve the performance and integration of semiconductor devices.
2. Catalyst field:
• Organic synthesis catalyst: can be used as a catalyst for acylation reaction, alkyd esterification reaction, olefin polymerization reaction and other organic synthesis reactions.It can form complex with organic matter, accelerate the reaction rate and increase the reaction yield.
• Petroleum catalytic cracking: In petroleum processing, it can be used as a catalyst for petroleum catalytic cracking to form a complex with asphaltene or hydrocarbon substances to promote the cracking reaction of petroleum and improve the yield and quality of fuel.
3. Material Science:
• Ultra-high temperature ceramic material: it is a precursor for the production of ultra-high temperature ceramics.Ultra-high temperature ceramics have excellent thermal stability and can be used in thermal protection systems, high-temperature structural components in the aerospace field, as well as in the manufacturing of cutting tools, crucibles, etc.
• Electronic material preparation: For the preparation of electronic materials, such as can be used as a precursor for the synthesis of lithium niobate, to provide niobium and chloride ions for the growth of materials and the formation of crystal structures;It also has certain application potential in the preparation of photovoltaic devices such as solar cells.
4. Metal surface treatment: can be used for metal surface treatment, such as steel, copper, aluminum and other metals corrosion protection.Soaking the metal surface in hafnium tetrachloride solution can form a protective film on the metal surface to effectively prevent further oxidation and corrosion of the metal.
5. Pharmaceutical field: It can be used for the synthesis and preparation of some drugs, such as the reaction with some organic compounds with anti-tumor activity, and has certain applications in the research and development of anti-cancer drugs.
6. Other fields: It can also be used in dyes, coatings, plastics and other fields as synthetic raw materials for some pigments to provide metal ions and chloride ions to change the color and properties of dyes.
