The acceptable atmosphere for CZ/Float-zone refining is essential in order to maintain the purity of the material being refined. It helps to prevent contamination from outside elements and ensures that the refining process is carried out under controlled conditions.
An inert gas atmosphere, such as argon or helium, is typically used for CZ/Float-zone refining. These gases do not react with the material being refined and help to maintain a stable environment for the process.
The atmosphere is maintained by continuously purging the chamber with the inert gas. This helps to remove any impurities and maintain a consistent environment for the refining process.
Yes, not having an acceptable atmosphere can result in contamination of the material being refined, leading to impurities and defects in the final product. It can also affect the accuracy and precision of the refining process.
The quality of the atmosphere can be monitored using gas sensors and analyzers to ensure that the levels of impurities and oxygen are within the acceptable range. Regular maintenance and calibration of these instruments are necessary to ensure accurate readings.
