| Abstract: | Coal ash rejected from the thermal power plant is usually used as raw mo(?)erial for making bricks, but its economic value may be raised to a higher level if it is refined. Microbeads can be used as filling powder of thermal insulition and high temperature resistance and the carbonaceous products can be also made from it if carbon content in the ash reaches more than 70%. |
