diamondANVILS.com are proud to offer synthetic sapphire anvils. In the first instance we are able to manufacture Diacell design anvils, both X=2.5mm and X=3.1mm, as well as Conical anvils of D=3.3mm/85deg.
Sapphire has almost no peaks above 1000 cm−1 in the Raman spectrum and no absorption in the ultraviolet range. It is therefore especially useful for studies in those spectral regions. Sapphire may be used as a substitute for diamonds in the pressure range up to about 20-25 GPa.
The synthetic sapphire used by diamondANVILS.com is grade 1, which means it is free of insertions, block boundaries, twins, microbubbles and scattering centers.
