|Description:||This micrograph is of a specimen which has been pressed from either side during fabrication, with the bright graphite flakes appearing edge on. Compare with micrograph 194.
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.
