ABRASION OF GLASS AS RELATED TO COMPOSITION

The abradability of glass of different compositions was estimated by grinding on a steel plate with powdered quartz as an abrasive, determining the weight removed from the ends of glass'rods, reducing this to volume, and comparing with the volume removed from used silica rods by the same treatm...

Description
Summary:The abradability of glass of different compositions was estimated by grinding on a steel plate with powdered quartz as an abrasive, determining the weight removed from the ends of glass'rods, reducing this to volume, and comparing with the volume removed from used silica rods by the same treatment. Silica (SiO2) and B2O2 are constituents contributing to resistance to abrasion, while soda, lime, and especially lead oxide produce high abradability. Abradabilities are expressed in numbers referred to silica glass as unity.
