Embodiment 1
[0036] With the general formula for synthesis (Zn 1-x mn x ) 2 SiO 4 The expressed zinc manganese silicate product 10g is example, and x represents the atomic number of Mn element in the formula, and x is 0.02, and the synthetic method used comprises the following steps:
[0037] 1. Preparation of amorphous silica gel
[0038] According to the general formula (Zn 1-x mn x ) 2 SiO 4 Weigh 9.38g (10.08mL) of tetraethyl orthosilicate, 10.08mL of deionized water, and 40.3mL of absolute ethanol, mix them, stir at 60-80°C for 1-2 hours to prepare a mixed solution, and use ammonia water with a weight concentration of 30% Prepare a pH adjusting solution with ethanol at a volume ratio of 1:5, adjust the pH of the mixed solution to 9-11, put it in an oven, bake at 80-100°C for 2-5 hours, and prepare an amorphous silica gel .
[0039] 2. Ingredients
[0040] According to the general formula (Zn 1-x mn x ) 2 SiO 4 Weigh 7.15 g of zinc oxide, 0.21 g of manganese carbonate, an...
Embodiment 2
[0048] With the general formula for synthesis (Zn 1-x mn x ) 2 SiO 4 The expressed zinc manganese silicate product 10g is an example, and x represents the atomic number of Mn element in the formula, and x is 0.02, and used raw material and synthetic method thereof comprise the following steps:
[0049] In this embodiment, the raw materials used are tetraethyl orthosilicate, zinc oxide, and manganese carbonate, and the amount of the raw materials is the same as in Example 1. The flux used is calcium fluoride, and the amount of calcium fluoride is 0.1 g. In step 3 of the sintering process, the sintering mixture is put into a crucible, placed in a high-temperature furnace, sintered at 1200° C. for 2 hours, and cooled naturally to room temperature. Other processing steps are identical with embodiment 1.
