Oxidation kinetics of low-oxygen silicon carbide fiber | …

The effect of partial pressure and temperature on the oxidation rate of low-oxygen silicon carbide fiber (Hi-Nicalon) has been investigated. The initial oxidation rate was described by a two-dimensional disc contracting formula for reaction control, and the activation energy was 155 kJ/mol. The rate at the later stage of oxidation obeyed the equation for diffusion control, and the activation

Solid Solubility of Aluminum and Boron in Silicon …

Solid solubility of aluminum in silicon carbide was studied by the powder X‐ray diffraction technique (Debye‐Scherrer method). At 2200° C the solubility limit was 1.0 wt%. Measurements of the lattice parameter of Al‐saturated samples as a function of temperature gave a heat of solution of 147 kJ/mol.
