Hafnium oxide uses and its properties

First, the basic properties of hafnium oxide

Hafnium oxide, also known as gallium oxide, with the chemical formula HfO2, is an inorganic compound. In nature, hafnium oxide mainly exists in the form of hafnium ores, rare earth minerals and other forms. Hafnium oxide is a white crystalline powder, odourless, non-toxic, insoluble in water, chemically stable. Hafnium oxide has excellent heat resistance, corrosion resistance, insulation, spectroscopic properties.

Second, the use of hafnium oxide

1. Aerospace field

Hafnium oxide is an important high-temperature material because it has very good heat resistance and thermal stability. In the aerospace field, hafnium oxide is widely used in rocket nozzle materials, gas turbine blades, aviation engine combustion chamber liner and other fields.

2. Electronic device field

Hafnium oxide is also an important material for electronic devices. Due to its excellent insulating properties, hafnium oxide is widely used in transistor devices, capacitor materials, high-frequency microwave devices, microprocessors and other electronic devices.

3. Glass ceramic field

Hafnium oxide is also commonly used in the production of high-temperature glass ceramics and other materials. Due to its chemical stability and good mechanical strength, hafnium oxide is widely used in the production of glass ceramic products, such as high-temperature kiln insulation board, thermocouple protection sheath.

4. Other fields

In addition, hafnium oxide is also used in laser compounds, arc welding flux, casting coatings, optical coating materials and other fields.
