Aremco Products, Inc. recently launched the Ceramabond™ 571, a new high temperature magnesium oxide based ceramic adhesive. It is used to bond thermocouples to high temperature molybdenum-rhenium heater tubes for applications to 3200o F (1760 ºC).
“Ceramabond™ 571 is ideal for assembling and insulating ceramic and metal components used in high temperature devices. It demonstrates exceptional electrical properties including a volume resistivity of 109 ohm-cm and dielectric strength of 255 volts per mil. Mechanical properties include tensile shear strength of 500 psi and torque strength of 21.6 ft-lbs,” according to Thomasnet.com.
Applications for Ceramabond™ 571 include the attachment of temperature probes and the fabrication of heaters, igniters, high power resistors, gas chromatographs, mass spectrometers, and oxygen analyzers.
