Trigonal crystal system; - RC; rhombohedral cell: ARH = 0.637 nm, a = 46 degrees 07';
Trigonal system, A0 = 0.313 nm, C0 = 0.474 nm, Z = 1. Brucite structure is one of the most important layered structures.
Hazard Characteristics: It can't burn itself. Toxic gases are released by high thermal decomposition.
