Abstract: The behaviour of circular discs, with 25 mm diameter and 2 mm thickness, made of commercial high-purity dense monolithic Alumina (RAPAL® 100) is evaluated under three different sequences of 100 heating-cooling cycles, all of them with a maximum temperature of 1200ºC. None of the different sequences of 100 cycles (even the most severe one with 100 cycles applied in 77 minutes, with maximum temperature of 1200°C and minimum temperature of 400°C) has caused noticeable alterations in the studied properties (density; Young´s modulus of elasticity; Coulomb´s modulus of elasticity; flexural strength) measured before and after the heat treatment.
