SYNTHESIS OF NANO-SCALED GLASS POWDERS USING THERMAL PLASMAS

摘要

A method for synthesizing nano-scaled glass powder using thermal plasma is provided to pass raw materials through high-temperature plasma flame to melt and fuse them and to cool off to obtain nano-scaled glass powder. A method for synthesizing nano-scaled glass powder using thermal plasma comprises: weighing raw materials and mixing them together; injecting the mixture into thermal plasma flame; fusing and vaporizing the injected mixture by high-temperature flame of the thermal plasma; cooling off the mixture and making them complex powder; and making the complex powder into a granular shape. The raw material is heated at lower temperature than sintering temperature so as to eliminate some of volatile components.
