The Sb2O3 glass was synthesized from chemically pure Sb2O3 crystals at 750 degrees C in vacuum. This glass is highly resistant to acid corrosion (e.g. HNO3, H2So4). Its properties include a density of 5.06 g/cm3; microhardness, 430 kg/mm2; initial softening temperature, 230 degrees; initial crystallization temperature, 273 degrees; crystallization capacity coefficient, 6.75; refractive index, 2.20; forbidden-band energy, 3.81 eV; and ultrasonic wave propagation rate, 2.62 x 10 power 5 cm/s. The ir spectrum of the glass is compared with that of the crystalline modifications senarmontite and valentinite.
