A HIGH PRESSURE CELL CAPABLE OF TEMPERATURES TO 1700 C AND PRESSURES TO 20,000 ATMOSPHERES.

Abstract

An apparatus has been designed and constructed for the study of high temperature materials under pressure. It consists of a modification of the simple piston-cylinder pressure system for simultaneous pressure and temperature application. The apparatus is capable of subjecting test specimens to pressures up to 20,000 atmospheres and temperatures to 1700 C. Temperatures were obtained by using an internal resistance furnace made of carbon - 10% silicon carbide. A relatively large specimen can be used, since the insulation consisting of mica and boron nitride has a maximum thickness of only 60 mils. The temperature can be accurately monitored and controlled by a unique specimen temperature calibration technique. This high temperature - high pressure cell will be used in sintering, phase transition, and compound formation studies. (Author)
