Background

Soda-lime glass makes up 90% of the global glass production and is used to make windows, glassware and bottles. Common raw materials include sodium carbonate (soda), calcium carbonate (limestone), calcium oxide (lime), dolomite, alumina, slags and sand (SiO2). Raw materials must be screened and mixed properly to give the desired glass properties for the finished products. Metal oxides such as CrO₃ and Fe₂O₃ impart color to the glass, and so must also be closely monitored during production. Final glass composition is then monitored to ensure the highest quality product. Rigaku NEX CG meets these measurements needs in a simple to use benchtop system, ideally designed for the at-line non-technical QC technician and the advanced technical user alike.
