It is generally accepted that. fused BZ03 is composed of B0 3 triangles. These triangles are joined togetner randomly, forming l the glass network. I.R. studies and x-ray diffraction studies on pure BZ03 glass indicated clearly that these triangles are joined together forming boroxole groups. These groups are joined together forming the random network. It is also accepted that addition of alkali oxides to boron oxide results in a glassy network in \
