Title: Stepan E Azoian: Innovator in Sapphire Tube Production
Introduction
Stepan E Azoian is a notable inventor based in Erevan, SU. He has made significant contributions to the field of materials science, particularly in the production of sapphire tubes. With a total of 2 patents to his name, Azoian's work has advanced the methods used in this specialized area.
Latest Patents
Azoian's latest patents include a method for producing sapphire tubes. This innovative process involves pulling sapphire tubes from a melt using a seed, while maintaining a longitudinal temperature gradient not exceeding 30 degrees Celsius per centimeter in the zone between the solidified front and the pulling region, where temperatures range from 1850 to 1900 degrees Celsius. The grown tube is then annealed at temperatures between 1950 and 2000 degrees Celsius, with a controlled increase in temperature at a rate of 30 to 40 degrees Celsius per minute, held for a duration of 3 to 4 hours. After this, the tube is cooled to room temperature at a similar rate. Azoian has also developed an apparatus that facilitates the maintenance of this temperature gradient during the tube pulling process.
