[0019] The preparation method of the above-mentioned yellow-green luminous glass-ceramic material, such as figure 1 As shown, the preparation process is as follows:
[0020] Step S1, according to the general chemical formula aCaO-bMgO-cSiO 2 -dEu 2 o 3 The number of moles of each component in the formula, weigh the source compound of CaO, the source compound of MgO, SiO 2 raw materials, and Eu 2 o 3 source compounds, mixed and ground into a mixed powder; wherein, a, b, c, and d are mole fractions and a+b+c=100; the value ranges of a, b, c, and d are respectively: 30≤ a≤50, 10≤b≤30, 30≤c≤50, 0.1≤d≤1
[0021] Step S2, pre-calcining the mixed powder at 1100-1300° C. for 1-6 hours, then cooling to room temperature, and grinding;
[0022] Step S3, under a reducing atmosphere, place the pre-calcined mixed powder again at 1200-1300°C for reduction treatment for 2-4 hours, and then cool to room temperature;
[0023] Step S4, adding 1% to 5% (weight) clarifier Sb to the mixed p...
