Sustainable small-scale spontaneous vapor explosion was proposed to utilize for the innovative rapid cooling and the liquid atomizing processes, namely the CANOPUS method. On the basis of CANOPUS method, a highly viscous coal gasification slag was atomized into 30μm powders for use of cement raw materials. The cooling rate of Al_<89>-Si_<11> particle was up to 1.5×l0^8K/s, which is more than 280 times higher than the conventional cooling method.
