Pickling is required in the production of quartz crucibles, but do you know what are the precautions to take when pickling it? If you don’t pay attention to it, it may produce precipitation and thus affect the quality of the product. Next, we will remind you of the following three points of attention in the pickling process of quartz crucible.
1. The material after pickling should not be exposed to the air until it has been rinsed sufficiently, because the material with residual acid on its surface will be easily oxidized in the air, thus producing blue or white mist.
2. The quartz crucible after pickling cannot be cleaned by ultrasonic before sufficient rinsing, because the ultrasonic tank is made of metal material, and the residual acid will react with the ultrasonic tank wall rapidly once it reaches the ultrasonic water, thus producing a large number of metal ions, which will mostly adsorb to the surface of the silicon material.
3. When drying the quartz crucible, the silicon material must not be in contact with any metal basket, because the deionized water on the surface of the silicon material is especially likely to produce a lot of heavy metal ions in the metal basket in the oven.
In the process of pickling quartz crucible, we need to pay attention to the above-mentioned content, only then can we guarantee the quality of the products in production.
