Abstract
The old technique of sandblasting which has been used for paint of scale removing, deburring and glass decorating has recently been developed into a powder blasting technique for brittle materials, capable of producing micro structures larger than $100{\mu}m$. Recently, this technique is applied to fabrication of the glass cap for OELD packaging. But, micro crack is generated on the blasted glass, which cause to decrease fracture strength. In this paper, we investigated the effect of blasting parameters on surface characteristics, surface shape and fracture strength of the powder blasted glass surface.
