摘要：
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 mum 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.
