The invention provides a ternary inorganic compound crystal with a molecular formula of Ca8Al12P2O31 and a preparation method of the ternary inorganic compound crystal. The preparation method comprises the following steps: respectively weighing a calcium salt, an aluminum salt and phosphate according to the molar ratio of calcium, aluminum and phosphorus in the molecular formula of Ca8Al12P2O31, calcining at the temperature of 1550-1570 DEG C, cooling, and grinding to obtain the ternary inorganic compound crystal. The invention also provides application of the ternary inorganic compound in binding materials and molecular sieves, nonlinear optical crystals and photochromic materials. |
