In 2018, Parkinson-Spencer Refractories Ltd embarked on the process of developing a glass contact material to provide enhanced operating life, primarily for feeder expandable refractories. The project began following a funded PhD research project carried out in collaboration with the School of Chemistry and Process Engineering at the University of Leeds. The chemical composition of the material incorporates a higher zirconia content (24.9%) than PSR's traditional feeder expandable materials. However, it is the back to first principles approach applied in order to achieve an optimum particle packing, high material density and low apparent porosity, which makes the material distinctive. The PSR-930 material has so far exhibited exceptional thermal shock resistance and high temperature glass corrosion resistance in soda lime silica glasses.
