Aremco Products Inc. has introduced a zirconia-phosphate-based machinable ceramic for the production of specialized brazing fixtures, induction liners, wafer chucks, optical stands and combustion nozzles for applications to 1550 °C. Aremcolox 502-1550 has a thermal expansion coefficient of 0.5 in./in./°F x 10-6. It is available in low- and medium-density compositions, both exhibiting a compressive strength of more than 25,000 psi, dielectric strength of 80 V/mil and thermal conductivity of 5.3 Btu-in./h-ft2-°F. The ceramic is available in 0.5- to 2.5-in.-diameter rods and in plates from 0.25 to 1 in. thick.
