Popis: This paper reports the bursting strength and Young's modulus values for bulk polycrystalline chemical vapour deposited (BP CVD) diamond using a differential pressure technique. The pressure-deflection data have a linear relationship and are analysed using plate theory. The results are presented for BP CVD diamond discs (14 and 25 mm in diameter and 179–319 μm thick), silicon, gallium arsenide and sapphire. Young's modulus values with a range of 986–1079 GPa and bursting strengths of 746–1138 MPa were calculated for BP CVD diamond.
