The market demand for tantalum pentoxide (tantalum anhydride) continues to grow, and it has broad application prospects in the electronics industry.

Tantalum pentoxide, also known as tantalum oxide and tantalum anhydride, has the chemical formula Ta2O5. It is a chemical substance and is the most common oxide of tantalum. Tantalum pentoxide appears as white or colorless crystalline powder with no special odor. It is soluble in molten hydrofluoric acid and potassium hydrogen sulfate, but insoluble in other acids and water. Tantalum pentoxide has the characteristics of strong bond energy and high melting and boiling point, and is widely used in chemical industry, electronic industry, metal smelting and other fields.

The main preparation methods of tantalum pentoxide include metal tantalum oxidation method and potassium fluorotantalate method. The metal tantalum oxidation method refers to using metal tantalum flakes as raw materials, adding hydrofluoric acid and nitric acid solutions, and producing tantalum pentoxide through processes such as dissolution, extraction, purification, precipitation, water washing, drying, roasting, and grinding; potassium fluorotantalate method It refers to using sulfuric acid and potassium fluorotantalate as raw materials, reacting the two under high temperature conditions, and then going through dilution, hydrolysis, precipitation, separation, cleaning, drying and other processes to obtain the finished product.

According to the “2023-2028 China Tantalum Pentoxide (Tantalic Anhydride) Industry Market In-depth Research and Development Prospects Forecast Report span>》shows that tantalum pentoxide is the main raw material of tantalum metal. Tantalum metal has the advantages of good ductility, moderate hardness, small thermal expansion coefficient, and good corrosion resistance.
