Ultra-lightweight C/SiC Mirrors and Structures

The milled green-body structure is then mounted in a high-temperature furnace and heated under vacuum to temperatures at which the metallic silicon changes into the liquid phase (about 1400ºC). The liquid silicon reacts with the carbon matrix and the surface of the carbon fibres to form a silicon-carbide matrix in a conversion process.

Emissivity Coefficients Materials

The emissivity coefficient - ε - indies the radiation of heat from a ''grey body'' according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal ''black body'' with the emissivity coefficient ε = 1. The emissivity coefficient - ε - for some common materials can be found in the table below. Note that the emissivity coefficients for some products varies with the temperature.
