Carbothermal reduction synthesis of TiB2 ultrafine powders

Ceramics International, 2016
Abstract Submicrometric TiB 2 powders were synthesized by carbothermal reduction process using titanium dioxide, boron carbide and carbon black as the starting materials. The influence of different amount of boron carbide (22.0–26.8 wt%), calcination temperature (1400–1900 °C) and holding time (15–90 min) on the composition and microstructure of the

Porous AlN Ceramics Fabricated by Carbothermal Reduction

Materials Science Forum, 2014
A new method for preparing porous AlN ceramics with high porosity had been developed by carbothermal reduction of die-pressed green bodies composed of alumina, carbon, sintering additives and AlN seeds. The influences of sintering additives and sintering temperature on the microstructure and mechanical properties of porous AlN ceramics were ...

Silicon assistant carbothermal reduction for SiC powders

Journal of University of Science and Technology Beijing, Mineral, Metallurgy, Material, 2008
The silicon assistant method to increase the reaction yield of carbothermal reduction of silica at a lower temperature is reported. The effect of silicon on the carbothermal reduction process has been investigated in detail. Compared with traditional reduction, the introduction of silicon can change the reaction path and further increase the conversion
