Silicon carbide ceramics with anisotropic pore microstructures pseudomorphous to wood were obtained by liquid Si infiltration of porous carbonized wood templates. Depending on the initial cellular microstructure of the various kinds of wood (ebony, beech, oak, maple, pine, balsa) ceramic materials of different density, pore structure and degree
A glassy carbon coated carbon foam material is formed by coating carbon foam with a glassy carbon layer. Carbon foam may be produced by carbonizing a phenolic or polyurethane foam at high temperatures in an inert atmosphere. The carbon foam is then machined to a desired shape and treated with a fine carbon or graphite powder to the surface.
