Thermomechanical properties of alumina fiber membrane

The use of an acid phosphate binder in place of a commercial silica colloid binder in the fabrication of an alumina fiber membrane was found to result in improved creep resistance (as tested under compression at 600 and 800 °C), increased flexural strength (as tested up to 800 °C), increased storage modulus and damping capacity (as tested up to 500 °C), and decreased thermal conductivity (as tested at 600 and 800 °C), in addition to the previously reported increased permeability and compressive strength at room temperature.
