Question

What is the chemical formula of high-purity alumina for circuit board substrates?

Answer 1

The chemical formula of high-purity alumina for circuit board substrates is Al₂O₃.

High-purity alumina is the basic material for manufacturing semiconductor components and printed circuit boards. It has good chemical stability, strong heat resistance, high dielectric properties and mechanical strength, and can meet the requirements of high temperature, high pressure, high speed, etc. of PCB substrates. Require.

High-purity alumina is a white amorphous powder, also known as aluminum oxide, with a molecular weight of 102. It is a chemical. It is an oxide of aluminum. It is a white solid at room temperature, is insoluble in water, and has a melting point of 2050℃, boiling point 2980℃, true density 3.98g/cm3.

Answer 2

Al₂O₃
Alumina is a stable oxide of aluminum with the chemical formula Al2O3.
Aluminum oxide, with the chemical formula Al₂O₃, is an important inorganic compound and the main oxide of aluminum. It is a white solid with high melting point and high hardness, and has good heat resistance, corrosion resistance and insulation properties. Alumina is widely used in many fields. For example, the substrate material used for printed circuit boards is aluminum oxide Al₂O₃.

Answer 3

Aluminum oxide is a stable oxide of aluminum with the chemical formula Al₂O₃. It is also called bauxite in mining, ceramics and materials science.
