Micron scandium powder
CAS No.: 7440-20-2
Appearance and shape: black powder
Melting point: 1539 ° C Boiling point: 2730 ° C
Uses:
First, in the application of new electric light sources, such as strontium-sodium lamp, the light emitted by the lamp is close to sunlight, with high luminosity, good light color, energy saving, long life and strong ability to break fog.
Second, in the application of laser, after GGG is added to 钪, it is made into GSGG, the transmission power is three times higher than other lasers of the same volume, and the requirements of high power and miniaturization can be achieved.
Third, the application in the alloy: in the alloy material is mainly used for alloy additives and modifiers. After adding antimony to aluminum and aluminum alloy, the overall performance of the alloy can be effectively improved. For example, the strength, hardness, heat resistance, corrosion resistance and weldability of the alloy are significantly improved.
Fourth, the application in other fields: such as the addition of antimony in the neutron filter material, in the nuclear fuel filtration, can prevent UO2 phase change, which is conducive to the operation. For example, a cathode gun containing bismuth is used in a color TV tube, which increases the power density of the gun by 4 times and the life of the cathode by 3 times.
