Embodiment 1
[0052] A kind of quartz crucible, its surface treatment process comprises the following steps:
[0053] S1. First, use a sandblasting machine to perform sandblasting on the outer surface of the quartz crucible. The nozzle of the sandblasting machine is 30° from the surface of the quartz crucible, and the distance from the quartz surface is 20 cm to obtain a quartz crucible with an average surface roughness Ra of 8 μm. ;
[0054] S2. Rinse the quartz crucible after sandblasting and cutting with tap water, and after rinsing, place it upside down on the shelf to drench off the water droplets on the surface;
[0055] S3. Place the washed quartz crucible in the treatment solution and soak for 60 minutes, and keep the temperature of the treatment solution at 35° C. to ensure that the treatment solution fully reacts with the surface of the quartz crucible;
[0056] S4, take out the quartz crucible soaked in the treatment solution, and rinse with deionized water;
[0057] S5. Baking...
Embodiment 2
[0060] A kind of quartz crucible, its surface treatment process comprises the following steps:
[0061] S1. First, use a sandblasting machine to perform sandblasting on the outer surface of the quartz crucible. The nozzle of the sandblasting machine is at 45° to the surface of the quartz crucible, and the distance from the quartz surface is 25 cm to obtain a quartz crucible with an average surface roughness Ra of 7 μm. ;
[0062] S2. Rinse the quartz crucible after sandblasting and cutting with tap water, and after rinsing, place it upside down on the shelf to drench off the water droplets on the surface;
[0063] S3. Soak the washed quartz crucible in the treatment solution for 60-90 minutes, and keep the temperature of the treatment solution at 40° C. to ensure that the treatment solution fully reacts with the surface of the quartz crucible;
[0064] S4, take out the quartz crucible soaked in the treatment solution, and rinse with deionized water;
[0065] S5. Baking the r...
Embodiment 3
[0068] A kind of quartz crucible, its surface treatment process comprises the following steps:
[0069] S1. First, use a sandblasting machine to perform sandblasting on the outer surface of the quartz crucible. The nozzle of the sandblasting machine is 60° from the surface of the quartz crucible, and the distance from the quartz surface is 30 cm to obtain a quartz crucible with an average surface roughness Ra of 10 μm. ;
[0070] S2. Rinse the quartz crucible after sandblasting and cutting with tap water, and after rinsing, place it upside down on the shelf to drench off the water droplets on the surface;
[0071] S3. Soak the washed quartz crucible in the treatment solution for 90 minutes, and keep the temperature of the treatment solution at 50° C. to ensure that the treatment solution fully reacts with the surface of the quartz crucible;
[0072] S4, take out the quartz crucible soaked in the treatment solution, and rinse with deionized water;
[0073] S5. Baking the rins...
