Embodiment 1
[0039] The basic composition of the glass is 0.2Yb 2 o 3 -1.5Al 2 o 3 -98.3 SiO 2 (mol%), F was introduced with F / Si=5wt% when preparing the sol. Under room temperature and magnetic stirring, according to Si(OCH 3 ) 4 :CH 3 OH:H 2 The molar ratio of O=1:4:2, using ammonia water as a catalyst, prepares a transparent sol liquid. Then according to the designed glass formula, add AlCl 3 ·6H 2 O and YbCl 3 ·6H 2 O and NH 4 F, Stir at room temperature for 1 hour to form a doped sol, and let it stand in a closed container until it gels; place the gel in a tube furnace at 600°C in an oxygen atmosphere for 12 hours to remove residual carbon and hydroxyl groups, Obtain silicon oxide powder; use ball milling equipment to ball mill the silicon oxide powder, and use a 150-mesh polytetrafluoro sieve to screen the powder with a particle size below 100 microns; place the sieved powder in a vacuum of 10 -3 Melt at 1650°C for 8 hours in a Pa high temperature furnace. The refracti...
Embodiment 2
[0041] The basic composition of the glass is 0.1Yb 2 o 3 -1Al 2 o 3 -98.9SiO2 2 (mol%), F was introduced with F / Si=5wt% when preparing the sol. Under room temperature and magnetic stirring, according to Si(OC 2 h 5 ) 4 :C 2 h 5 OH:H 2 The molar ratio of O=1:4:2, using hydrochloric acid as a catalyst, prepares a transparent sol liquid. Then according to the designed glass formula, add AlCl 3 ·6H 2 O and YbCl 3 ·6H 2 O and (NH 4 ) 2 SiF 6 , stirred at room temperature for 10 hours to form a doped sol, which was left to stand in a closed container until gelation; the gel was placed in a tube furnace and kept at 1000°C for 8 hours to remove residual carbon and hydroxyl groups, and obtained Silica powder; use ball milling equipment to carry out ball milling to the described silica powder, and use a 150-mesh polytetrafluoro sieve to screen out the powder with a particle size below 100 microns; place the sieved powder in a vacuum of 10 -3 Melt at 1750°C for 3 hours ...
Embodiment 3
[0043] The basic composition of the glass is 0.1Yb 2 o 3 -1Al 2 o 3 -98.9SiO2 2 (mol%), F was introduced with F / Si=10wt% when preparing the sol. Under room temperature and magnetic stirring, according to Si(OC 2 h 5 ) 4 :C 2 h 5 OH:H 2 The molar ratio of O=1:20:10, using hydrochloric acid as a catalyst, prepares a transparent sol liquid. Then according to the designed glass formula, add AlCl 3 ·6H 2 O and YbCl 3 ·6H 2 O and NH 4 F, Stir at room temperature for 2 hours to form a doped sol, and let it stand in a closed container until it gels; place the gel in a tube furnace under an oxygen atmosphere and 1000°C for 8 hours to remove residual carbon and hydroxyl groups, Obtain silicon oxide powder; use ball milling equipment to ball mill the silicon oxide powder, and use a 150-mesh polytetrafluoro sieve to screen the powder with a particle size below 100 microns; place the sieved powder in a vacuum of 10 -3 Melt at 1750°C for 3 hours in a Pa high temperature furn...
