Rustum Roy
Formula:
Ca10(Si2O7)2(SiO4)(OH)2Cl2
Colour:
Colourless
Specific Gravity:
2.94 (Calculated)
Crystal System:
Monoclinic
Name:
Named in honor Rustum Roy (July 3, 1924, Ranchi, Bihar, India – August 26, 2010, State College, Pennsylvania, USA), professor at Pennsylvania State University and a specialist in the crystal chemistry of minerals and synthetic materials. He was a co-founder of the Materials Research Society, and elected to five National Academies of Engineering/Science. He developed the sol-gel process and identified the phases of barium titanate, an important material used to make capacitors in the electronics industry. Dellaite is named after his wife, Della Roy.
