The Effect of Hot Isostastic Pressing on the Optical Properties Of Spinel

Abstract

The effect of different hot isostatic pressing (HIP) temperatures and pressures on the optical transmission of hot pressed spinel was studied. The transmittance and extinction coefficient were measured. The transmittance data was used to determine the relative size of the scattering sites. HIP temperatures as low as 1500 degree C were seen to be effective in increasing the transmittance. The transmittance increased with increasing HIP temperature and pressure. The size of the scattering sites were large relative to the wavelengths of light measured. Interestingly the size of the scattering site was found to increase with increasing HIP temperature and pressure.
