Available Grades and Materials

We offer premium Ta-1 grade tantalum lumps that meet international quality standards. Our materials are carefully selected and processed to ensure consistent chemical composition and physical properties. Custom specifications are available upon request to meet your specific requirements.

Manufacturing Process

Our tantalum lumps are produced through advanced electron beam melting technology. This process involves:

1. Raw material selection and purification
2. Horizontal electron beam furnace melting
3. Controlled cooling and solidification
4. Quality inspection and testing
5. Size sorting and packaging

This refined process ensures superior quality and eliminates impurities that could affect your final products.

Two processes for producing tantalum blocks

Carbon reduction tantalum bar process flow C+Ta2O5( Nb2O5）→Ta（Nb)+CO ↑

Sodium reduction tantalum bar process flow (K2TaF7+5Na=Ta+5NaF+2KF )
