Product Name:Tantalum
English Name:Tantalum
CAS No.:7440-25-7
Aliases:Tantalum powder, Nano tantalum powder
Molecular Formula:Ta
Physical Properties:Black to gray-black regular spherical powder with high purity, fine particle size, uniform particle distribution, large specific surface area and low apparent density. Theoretical density 16.6 g/cm³, melting point 2996 °C, boiling point 5425 °C.
Uses:Tantalum is widely used in chemical, electronic, military, mechanical, aerospace and other industries for manufacturing electronic components, heat-resistant materials, corrosion-resistant equipment, catalysts, molds and optical glass. In medicine, it is used as human implants, surgical materials and contrast agents. In the electronics field, micro/nano tantalum powder is used in tantalum capacitors to form extremely thin insulating layers, enabling high capacitance in smaller dimensions and promoting the development toward miniaturization and high capacity.
