Carbon substitution for oxygen in α–cristobalite

We investigated the carbon solubility into silica under high temperature condition. Mixtures of amorphous silica and graphite powder sealed in silica glass tubes were heated at 1300 °C. The a lattice parameter and unit cell volume of α–cristobalite obtained are slightly increased compared with that...
