Effect of Mg particle sizes on synthesis of mesoporous silicon carbide by magnesiothermic reduction process

Fabrication of SiC and Si3N4Whiskers under Pressurized Ar and N2Atmosphere through High-Energy Ball Milling

“…The unwanted impurities were removed from the product powder by room‐temperature acid treatment in a mixture of 10 wt% HF and 2 M HCL for 5 h, filtration, washing with distilled water, and drying at room temperature (24 h). The mesoporous silica had similar Brunauer–Emmett–Teller data as previously reported (total pore volume, average pore diameter, and BET surface area of 0.7 cm 3 /g, 2.2 nm, and 1200 m 2 /g, respectively) . High‐energy ball milling was carried out in a planetary ball mill at 600 rpm using a ball‐to‐powder mass ratio of 55:1 (total powder mass = 2 g).…”
