2. Metallurgical grade tantalum powder
Suitable for powder metallurgy to produce various tantalum processing materials and alloy additives.

3.Medium and high pressure tantalum powder

FTP series sheet tantalum powder is a kind of tantalum powder with original particle as flake. Compared with sodium-reduced tantalum powder, this kind of tantalum powder has the advantages of larger Ferri particle size, smaller specific surface area and simpler grain shape. It has good sintering resistance, high reliability and high voltage resistance. It is especially suitable for making medium and high voltage solid tantalum electrolytic capacitors with high reliability requirements of 20~63V
