A ceramic board (1), of at least cement and gypsum, preferably in the proportions 1:10, and can include additional filler material in the composition. The board is used for various applications including as a door panel (31) or cabinet door (81). The board (21) can have channels, grooves, honeycomb, corrugations, or protrusions (22) extending along one or both faces which help to lighten the board whilst retaining rigidity, and which can have filler material (103) provided therein. The board (31) can have mounting points (35) for cabinet hinges or a lock, and can have internal strengthening members (142a,b,c) within the material of the board. The board or door can have an edge protector, which can be internal (153) or external (112). An end of the board can form a recess (184) for cables, pipes etc, which can be formed by internal strengtheners protruding from the end of the ceramic material (FIGS. 18a, 18b). The board can have an internal frame or skeleton embedded within the ceramic material.
