Abstract
A high temperature‐highpressure pyrophyllite cell with a graphiteheater has limitations when temperature exceeds ∼2100 K. A conventional cell used with the cubic anvil high pressure apparatus has been modified to reach ∼3300 K. The heater power versus temperaturecalibration curve has been established using Pt–Pt10%Rh thermocouple up to 1900 K. For calibration above 1900 K, the heater powers required to initiate melting in Al2O3, Y2O3, and TiB2, and decomposition of α‐SiC have been determined. The melting (or decomposition) of the specimens has been detected by examining the microstructure of the specimens recovered after pressure‐temperature treatment.Keywords
