Scandium Powder

Scandium Powder offers high surface area, excellent reactivity, and uniform particle size, making it ideal for applications in alloying, advanced ceramics, and catalysis. The powder format allows even distribution in composite materials, rapid dissolution in reactive melts, and homogeneous coating in deposition processes. Industries such as aerospace, energy, and electronics use scandium powder for producing high-strength alloys, enhancing solid oxide fuel cell performance, and fabricating high-performance ceramic components. Specific applications include grain refinement in aluminum alloys, improving ionic conductivity in fuel cell electrolytes, and producing advanced optical ceramics. In research, scandium powder supports studies on rare-metal catalysis, alloy development, and materials synthesis.
