Embodiment 1
[0020] Embodiment 1: adopt Na 2 O-B 2 o 3 -NaF flux to prepare Na 3 La 9 B 8 o 27 the crystal
[0021] Take Na 3 La 9 B 8 o 27 Powder (synthesized according to the method disclosed in Chinese patent application 01134393.1) and analytically pure Na 2 CO 3 、H 3 BO 3 , NaF as raw material, molar ratio Na 3 La 9 B 8 o 27 :Na 2 CO 3 :H 3 BO 3 : NaF = 1: 5: 4.6: 13.13 ingredients, weigh 110 grams of Na 3 La 9 B 8 o 27 Powder, 31.723 g Na 2 CO 3 , 17.026 g H 3 BO 3 , 33 grams of NaF, that is, the molar ratio of Na in the growth system 3 La 9 B 8 o 27 :Na 2 O: B 2 o 3:NaF=1:5:2.3:13.13. Sodium carbonate in the raw material can be replaced by a corresponding amount of sodium nitrate, sodium oxalate, and sodium hydroxide; boric acid can be replaced by a corresponding amount of boron oxide. Grind and mix the weighed raw materials evenly, place them in a corundum crucible, put them in a muffle furnace and raise the temperature to 500°C, and keep the te...

[0022] Embodiment 2: adopt Na 2 O-B 2 o 3 -NaF flux to prepare Na 3 La 9 B 8 o 27 the crystal
[0023] Take Na 3 La 9 B 8 o 27 Powder (synthesized according to the method disclosed in Chinese patent application 01134393.1) and analytically pure Na 2 CO 3 、H 3 BO 3 , NaF as raw material, molar ratio Na 3 La 9 B 8 o 27 :Na 2 CO 3 :H 3 BO 3 : NaF = 1: 6: 6: 13.13 ingredients, weigh 110 grams of Na 3 La 9 B 8 o 27 Powder, 38.067 g Na 2 CO 3 , 22.207 g H 3 BO 3 , 33 grams of NaF, that is, the molar ratio of Na in the growth system 3 La 9 B 8 o 27 :Na 2 O: B 2 o 3 :NaF=1:6:3:13.13. Sodium carbonate in the raw material can be replaced by a corresponding amount of sodium nitrate, sodium oxalate, and sodium hydroxide; boric acid can be replaced by a corresponding amount of boron oxide. Grind and mix the weighed raw materials evenly, place them in a corundum crucible, put them in a muffle furnace and raise the temperature to 500°C, and keep the tempe...
Embodiment 3
[0024] Embodiment 3: adopt Na 2 O-B 2 o 3 -NaF flux to prepare Na 3 La 9 B 8 o 27 the crystal
[0025] Take Na 3 La 9 B 8 o 27 Powder (synthesized according to the method disclosed in Chinese patent application 01134393.1) and analytically pure Na 2 CO 3 、H 3 BO 3 , NaF as raw material, molar ratio Na 3 La 9 B 8 o 27 :Na 2 CO 3 :H 3 BO 3 : NaF=1: 7.54: 6.46: 8.756 ingredients, weigh 100 grams of Na 3 La 9 B 8 o 27 Powder, 43.480 g Na 2 CO 3 , 21.741 g H 3 BO 3 , 20 grams of NaF, that is, the molar ratio of Na in the growth system 3 La 9 B 8 o 27 :Na 2 O: B 2 o 3 :NaF=1:7.54:3.23:8.75. Sodium carbonate in the raw material can be replaced by a corresponding amount of sodium nitrate, sodium oxalate, and sodium hydroxide; boric acid can be replaced by a corresponding amount of boron oxide. Grind and mix the weighed raw materials evenly, place them in a corundum crucible, put them in a muffle furnace and raise the temperature to 500°C, and keep ...
