Next, the waste glasses were ground in a ring mill for 5 hours to obtain the silica powder with the maximum size of 63 µm. The finer the particle size obtained, the reactivity would be higher thus silica carbide would be produced at lower temperature. The ratio of mixing SiC composition is three carbon powders to one silica powder.
