  • Temperature change rate should not exceed 150°C (302°F) per hour
  • High-alumina products are highly refractory, meant for use in reducing and oxidizing atmospheres
  • Material is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalis and other fluxes
  • Recommended for use with refractory metals
  • Suitable for glass melting, including borosilicate glass
