Title: Kliment A Kostandian: Innovator in Sapphire Tube Production

Introduction

Kliment A Kostandian is a notable inventor based in Yerevan, Armenia. 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, Kostandian's work has implications for various high-tech applications.

Latest Patents

Kostandian's latest patents focus on methods for producing sapphire tubes. The first patent describes a method where sapphire tubes are pulled from a melt using a seed. The process maintains a longitudinal temperature gradient not exceeding 30 degrees Celsius per centimeter in the zone between the solidified front and the pulling region, which operates at temperatures between 1850 and 1900 degrees Celsius. The grown tube is then annealed at temperatures ranging from 1950 to 2000 degrees Celsius, with a controlled increase in temperature at a rate of 30 to 40 degrees Celsius per minute. This annealing process lasts between 3 and 4 hours, followed by a cooling phase to room temperature at the same rate. An apparatus is also disclosed to maintain the required temperature gradient during the tube pulling process.
