✦ Synopsis

Terahertz frequency transmission measurements on ceramic boron nitride and aluminium nitride are described. The absorption coefficients and refractive indices of these materials show that they have high terahertz transparency, which together with their high melting temperatures and mechanical strength makes them particularly suitable for use as THz windows in high pressure and/or high temperature applications.
