example 1
[0040] Example 1 Yellow Luminous Jade
[0041] Select a=2.0, b=1.1, c=1.8, d=0.01, e=0.03, f=0.1, g=0.05, h=0, M=Sr 0.05 Ca 0.95 , M'=Mg 0.95 Zn 0.05 , β=0
[0042] raw material
[0043] The above-mentioned raw materials are weighed according to the weight ratio, and after finely blending, they are pressed into a cylinder under a pressure of 10 MPa, put into a plastic mold, and further compacted by 200 MPa cold isostatic pressing, and the atmosphere is 90% N 2 +10%H 2 In a reducing atmosphere furnace, the temperature is gradually raised to 1150°C, and after a constant temperature of 5 hours, it is gradually lowered to room temperature to obtain a yellow luminescent artificial luminescent jade.
example 2
[0044] Example 2 Blue Luminous Jade
[0045] raw material
[0046] Weigh the above raw materials according to the weight ratio, grind and mix them evenly, and put them into the mold of the hot-press furnace, and the atmosphere is 95% N 2 +5%H 2 In a reducing atmosphere, gradually raise the temperature and pressurize to 1000°C, under 30MPa, sinter for 1 hour, and gradually lower to room temperature to obtain artificial luminous jade with luminous blue color.
example 3
[0047] Example 3 dark blue luminous jade
[0048] raw material
[0049] The above-mentioned raw materials are weighed according to the weight ratio, and after finely mixing, pass through H 2 Sinter in a high-temperature furnace at 1300°C for 4 hours. After cooling, grind the massive sintered body finely. After passing through a 400-mesh sieve, compact the sieved powder into a certain shape with an aqueous solution of CMC. After drying, In the high-temperature furnace with N2, the temperature is gradually raised to 1420°C, and after 5 hours of constant temperature, it is gradually lowered to room temperature to obtain artificial luminescent jade with a dark blue luminescence.
