Embodiment 1
[0027] The composition of this example is only doped with trace amounts of NiO and Yb 2 o 3 . The preparation method of the transparent glass-ceramics in this example is as follows: Weigh about 50 g of raw materials according to the composition ratio of Example 1, grind them in an agate mortar for 30 minutes, and then put them in a platinum crucible and melt them at 1550° C. for 2 hours; The melt is quickly poured on a stainless steel plate, and lightly flattened with another steel plate, then transferred to the muffle furnace and annealed at 550°C for 2 hours, then turn off the power of the muffle furnace and let the glass cool down to room temperature with the furnace, and it will become transparent after taking it out Glass, slightly yellow in color. Put the transparent glass sample into the muffle furnace and raise it from room temperature to 650°C at a rate of 300°C / h, keep it warm for 10 hours, then turn off the power of the muffle furnace and let the glass sample drop...
Embodiment 4 to Embodiment 7
[0031] The four examples are doped with different levels of Yb 2 o 3 , while the content of NiO was fixed at 0.1 mol%. The preparation method of transparent glass-ceramics is as follows: Weigh about 50 g of raw materials according to the composition ratio of the four examples, grind them in an agate mortar for 30 minutes, then place them in a platinum crucible and melt them at 1600°C for 2 hours; Quickly pour the liquid on a stainless steel plate, and lightly flatten it with another steel plate, then transfer it to a muffle furnace and anneal at 550°C for 2 hours, then turn off the power of the muffle furnace and let the glass drop to room temperature with the furnace, and take it out to get a transparent glass , are brown-yellow. Put the transparent glass sample into the muffle furnace and raise it from room temperature to 680°C at a rate of 300°C / h, keep it warm for 10 hours, then turn off the power of the muffle furnace and let the glass sample drop to room temperature wi...
Embodiment 8 to Embodiment 11
[0033] The four examples are doped with higher content of NiO and Yb 2 o 3 . The preparation method of transparent glass-ceramics is as follows: Weigh about 50 g of raw materials according to the composition ratio of the four examples, grind them in an agate mortar for 30 minutes, and then place them in a platinum crucible and melt them at 1600°C for 2 hours; glass The melt is quickly poured on a stainless steel plate, and lightly flattened with another steel plate, then transferred to the muffle furnace and annealed at 550°C for 2 hours, then turn off the power of the muffle furnace and let the glass cool down to room temperature with the furnace, and it will become transparent after taking it out Glasses; the glass of Example 8 was yellowish brown, the remaining three were brown. Put the transparent glass sample into the muffle furnace and raise it from room temperature to 700°C at a rate of 300°C / h, keep it warm for 10 hours, then turn off the power of the muffle furnace ...
