Mg–Zn–Ca powders of Mg63+xZn32−xCa5 (x=0, 3, 7 and 10) with the diameter from 2μm to 180μm were synthesized by gas-atomization. The relationship among powder morphology, the composition, glass forming ability, thermal stability, corrosion resistance and the capacity in degrading azo dyes for these powders was investigated. It is shown that fully glass powders with the particle diameter |
