The glass formation of the aluminoborates of Group II metal oxides depends on the atomic weight of the oxide and on the electronic configuration of the metal ion. The participation of zinc, cadmium, and magnesium ions as network formers in the glass is shown from measurements of thermal expansion. The linear thermal expansion of the alkaline‐earth aluminoborates varies from 4.7 × 10 −6 to 16 × 10 −6 per °C.
