Product Description

Find 1600ºC,1700ºC ,1800ºC,1900ºC Ceramic Board [polycrystal] for Your Kilns,furnaces

NR® high-density ultra high temperature ceramic fiber board products are available in formulations for service temperatures up to 1800°C.  NR® high-density boards are available for high temperature, oxidizing environments  and high temperature, reducing environments . NR® boards are formed from alumina or mullite polycrystalline fibers with appropriate inorganic and organic binders. All grades are pre-fired to 1000°C or greater, resulting in an organic free composition. Possible applications include furnace hearth plates and low mass sintering setters.

Features

• High temperature stability, good performance against heat shock and erosion.
• Low heat capacitance, low thermal conductivity.
• Hard and high internal adhesive strength allow it with good performance for machining and cutting.
• Can have direct contact with flame, easy for installation and use.

Application scope:

• Ceramic industry: kiln liner, kiln car
• Glass industry
• Piping heat insulation, common heat resisting material
• Other high temperature insulation
