Morgan Advanced Materials has announced the launch of a new range of furnace products made from fully stabilised zirconia which offer extensive performance benefits in temperatures of up to 2,000ºC (3,632ºF) in a variety of industrial process applications.

Fully stabilised zirconia has been developed by Morgan to deliver resistance to chemical corrosion and temperatures, with a long and reliable service life. Boasting flexural strength of 200MPa and thermal conductivity of 1.5 – 3.0 Wm-1K-1 at 200ºC (392ºF).

Products available include sheath tubes for temperature monitoring, suitable for atmospheres containing carbon commonly used in DSS furnaces for the production of photovoltaic silicon ingots. Their design allows the easy incorporation and protection of an interior sheath tube and insulation rod.

Meanwhile, a range of crucibles is available in calcium fully stabilised zirconia (CaO-FSZ) which possesses excellent refractory properties as well as high resistance to the alkalis, acids and caustic chemicals encountered in chemical processing applications.

Manufactured to extremely tight tolerances, the high purity of these products delivers outstanding stability in a full range of thermal processes. As well as standard sizes and shapes, designs can be customised to meet individual application requirements.
