This is because it is a highly crosslinked solid. The network is held together by both covalent bonds and a large number of hydrogen bonds, which tie otherwise independent parts of the network together. The network is frozen in place and is probably glassy.

  • Coal Coal types Britannica

    Coal types Macerals. Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water (or wind activity) or of minerals such as pyrite and marcasite that formed in place (authigenic). Some formed in living plant tissues, and others formed later during peat Frontiers Factors Affecting Brittleness Behavior of Coal ,Coal gangue, which is the solid waste produced during the coal processing, causes serious environmental problems. Lightweight concrete by making use of the coalgangue ceramsite as the aggregate has many advantages as the construction material. However, the high brittleness of lightweight aggregate concrete is one of the problems for Coal Fuels & Technologies IEA,The world’s coal consumption is set to reach a new high in as the energy crisis shakes markets.
