Synthesis of Al<sub>4</sub>SiC<sub>4</sub> powders via carbothermic reduction
Reaction and grain growth mechanisms
Highly pure Al4SiC4 powders were prepared by carbothermic reduction at 2173 K using Al2O3, SiO2, and graphite as raw materials. The obtained Al4SiC4 powders owned hexagonal plate-like grains with a diameter of about 200–300 μm and a thickness of about 2–6 μm. Based on the experim

In this paper, the fabrication and thermal conductivity (TC) of
water-based nanofluids using boron (B)-doped SiC as dispersions are
reported. Doping B into the β-SiC phase leads to the shrinkage of
the SiC lattice due to the substitution of Si atoms (0.134 nm radius)
by small

The easy-going oxidation of silicon nitride (Si3N4) at high temperature greatly hampers its potential applications. Here, we explored the reaction mechanism between β-Si3N4 and O2 via density functional theory (DFT) calculation, which discloses that O atoms are preferentially ads

Aluminum nitride (AlN) with a combination of very high thermal conductivity and excellent electrical insulation properties exhibits wide applications. However, it is quite sensitive to a moist environment and hydrolyzes sl
