Figures 3 G–3L demonstrate the mechanical compressibility of the two distinct carbonaceous materials. Both types of carbonaceous blocks can be compressed by >80% as a result of their high porosity. However, the WC block is highly fragile and deforms permanently (collapsed into small pieces) when compressed by >80% (Figures 3 G–3I).
