The raw materials and the processes adopted for the manufacture of the parts retain their properties, including dimensional stability, impermeability and resistance. According to the requirements for its useparts the products can be made in high alumina or mullite. In case of alumina thermocouple protection tubes the products are chemically more resistant, harder, stronger and more refractory than the mullite tubes. Its typical uses are: noble metal thermocouple protection, furnace tubes, high temperature vacuum furnaces, radiant tubes, laser tubes, abrasives and corrosive environments, electrical insulations applications. They are recommended for use with platinum, tungsten and molybdenum thermocouples. In the case of the mullite products they can be used in insulators, in furnace muffles, combustion tubes, radiant furnace tubes. Materials and processes used to manufacture these pieces give high resistance to atrition, thermal shock, corrosion, maintaining good electrical insulation, wearing and abrasive resistance, and support high temperatures and harsh environments.
