Embodiment 1
[0032] The preparation method of the modified jade powder of the present embodiment comprises the following steps:
[0033] 1) Raw material preparation: natural jade crushed stone powder and transition metal oxide are mixed in a weight ratio of 10:1 to obtain a mixed powder;
[0034] 2) Multi-phase composite: put the mixed powder in a muffler furnace, heat up to 550°C at a rate of 5°C / min, and continue calcining for 2 hours to obtain high-temperature multi-phase composite jade powder;
[0035] 3) Quenching and hydration: quickly place the high-temperature multi-phase composite jade powder in a saturated aqueous solution of magnesium hydroxide with a pH of 10-11, soak for 3 hours, filter, and wash repeatedly until the filtrate is acid-base neutral, and then stand for aging after filtering After 12 hours, place it in an oven at 80°C for 10 hours and dry it for 10 hours. The moisture content is lower than 10%, and the processed jade powder is obtained;
[0036] 4) Superfine crus...
Embodiment 2
[0038] The preparation method of the modified jade powder of the present embodiment comprises the following steps:
[0039] 1) Raw material preparation: natural jade crushed stone powder and transition metal oxide are mixed in a weight ratio of 10:1 to obtain a mixed powder;
[0040] 2) Multi-phase composite: put the mixed powder in a muffler furnace, heat up to 550°C at a rate of 5°C / min, and continue calcining for 2 hours to obtain high-temperature multi-phase composite jade powder;
[0041] 3) Quenching hydration: In a fume hood, quickly place the high-temperature multi-phase composite jade powder in an ammonia-ammonium chloride aqueous solution with a pH of 10-11 and soak for 3 hours, filter, and wash repeatedly until the filtrate is acid-base neutral And there is no ammonia smell. After filtering, let it stand for aging for 12 hours, and dry it in an oven at 80°C for 10 hours. The moisture content is less than 10%, and the treated jade powder is obtained;

Embodiment 3
[0044] The preparation method of the modified jade powder of the present embodiment comprises the following steps:
[0045] 1) Preparation of materials: natural jade crushed stone powder and transition metal oxides are mixed at a weight ratio of 10:0.8;
[0046] 2) Multi-phase composite: put the mixed powder in a muffler furnace, heat up to 800°C at a rate of 8°C / min, and continue calcining for 2 hours to obtain high-temperature multi-phase composite jade powder;
[0047] 3) Quenching and hydration: quickly place the high-temperature multi-phase composite jade powder in a saturated aqueous solution of magnesium hydroxide with a pH of 10-11, soak for 3 hours, filter, and wash repeatedly until the filtrate is acid-base neutral, and then stand for aging after filtering After 12 hours, place it in an oven at 80°C for 10 hours and dry it for 10 hours. The moisture content is lower than 10%, and the processed jade powder is obtained;
