Mold for producing silicon ingot and method for fabricating the same

Abstract

A mold for producing a silicon ingot having a layered structure comprising an inner silica layer containing at least one layer in which a fused silica powder with a particle size of 100 μm or less and a fine fused silica sand with a particle size of 100-300 μm is bonded with a silica binder, and an outer silica layer containing at least one layer in which a fused silica powder with a particle size of 100 μm or less and a coarse fused silica sand with a particle size of 500-1500 μm is bonded with a silica binder.
