Embodiment 1
[0038] A green preparation process for optical fiber using zirconia-based cermet materials, including:
[0039] S1. Weigh magnesium nitrate, cerium nitrate, scandium nitrate, calcium nitrate, and lanthanum nitrate according to the mass ratio of 1:2:2:0.5:1, then add deionized water, mix evenly, and configure 25% nitrate mixture solution;
[0040] S2, add 10% citric acid solution to the mixed nitrate solution, and stir evenly;
[0041] S3. Raise the temperature of the mixed solution to 75°C, and at the same time slowly add ammonia water with a concentration of 30% with a peristaltic pump, and keep stirring until a gel precipitate is formed, and the obtained gel precipitate is repeatedly washed to remove excess residual water-soluble ions, and then dried;
[0042] S4. Take the designed amount of metal powder and alumina-based ceramic powder and place them in a high-speed ball mill for mixing and grinding for 3 hours. The speed of the high-speed ball mill is 450 rad / min, and then...
