Paper Abstract

Glass lightweight mirror can be made by Hot Isostatic Atmospheric Pressure (HIAP) casting method which melting small glass chunks into a mold that made lots of hexagon-shaped pockets in the back of the mirror. Alumina-silica refractory cores which used to form honeycomb mold can withstand over 950 degree Celsius temperature. Furnace temperature rises to 950 degree Celsius after H4 H-K9L chunks loaded into mold, holds this temperature over 2 hours and then drops to room temperature slowly. HIAP casting lightweight blank can used to form 1/60 λ RMS (λ=0.6328μm) mirror and this method can use to made big diameter lightweight blank.
