METHOD OF MANUFACTURING OPTICAL DEVICE MATRIX CONSISTING OF TRANSPARENT SILICA AND ALUMINO-SILICATE GLASS BY PULSE ELECTROHEATING PROCESS

摘要

PROBLEM TO BE SOLVED: To manufacture silica and alumino-silicate glass having transparency by using a pulse electroheating process and to utilize them as an optical device matrix. SOLUTION: The above silica and glass are manufactured by mixing silica and alumina powder of a grain size from 0.1 to 500μm and using the pulse electroheating process capable of controlling square wave electric current from 2 to 20 kA and pressure from 10 MPa to 5 GPa.
