    摘要: Shaped synthetic diamond articles are fabricated by vapour deposition of synthetic diamond on releasable moulds. A process is also provided for forming a shaped synthetic diamond article by coating a mould with an etchable layer and then depositing synthetic diamond on the etchable layer; the etchable layer is thereafter removed in an etchant bath, releasing the diamond article from the mould. The synthetic diamond articles are useful as high-­temperature, corrosion resistant vessels and as wear surfaces.
