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.

Abstract

A luminous jade has a chemical formula: aM beta.bM'beta.cSiO2.dAl2O3.eEu2O3.fB2O3.gLn2O3.hZrO2, where M is one or more of Ca, Sr, Ba, Mg, Zn and Cd; M' is one or more of Be, Mg, Zn and Cd; beta is one or both of O and S; Ln is one or more of Ce, Pr, La, Dy, Ho, Nd, Er, Bi, Ga, Sb, Lu, Y, Mn, Mo, Cr, Sn, Cu and Tm; and a,b,c,d,e,f,g and h are mole ratios. It is prepared through mixing and high-temp sintering, and features compact mass, high toughness, and long luminous time after radiated by light.

Description

technical field [0001] The invention relates to artificial luminous jade technology, in particular to artificial luminous jade with light storage-luminescence properties and a manufacturing method thereof. Background technique [0002] Jade refers to a natural ore with a hardness of 3 degrees to 7 degrees, dense texture and toughness. After being processed into various handicrafts, it has high ornamental, use and collection value. But jade is all natural thing, and resource is limited, and its price is expensive in addition and is difficult to be accepted by the public. The grape wine luminous cup mentioned in the ancient poems does not emit light, but the wall of the jade cup is thin and transparent, and there is a luminous effect under the light. In recent years, imitation jade products have continuously appeared in the market, and the quality has also been continuously improved. Most of them are made of polymer materials as the main raw material....
