|Description:||This micrograph is of a specimen which has been pressed parallel with your nose (into the screen) during fabrication, with the bright graphite flakes appearing face on. Compare with micrograph 193.
The MgO grain is polycrystalline and porous. The anisometric microstructure means the brick properties are anisotropic and so the bricks orientation must be carefully controlled on installation. These are true composite materials using ceramic (MgO, natural graphite), metal (Si, Al additives), and polymer (phenolic resin) components.
