  • Heat-resistant porous structural material
    Patent number: 4035545
    Abstract: A material, comprising 50-75 volume percent of microspheres of high-melting point oxides, sintered directly with each. The diameter of said microspheres ranges from 10 to 200 mu. The diameter of contact of said sintered microspheres amounts to 0.2-0.5 of said microsphere diameter.The present invention enabled an enhancement of recrystallization resistance, strength and deformability of said heat-resistant porous structural material. Thus, a material made of microspheres of stabilized zirconium oxide, 30-40 mu in diameter, with a contact diameter equal to 0.3 of the microsphere diameter and a 30% porosity exhibits a compression strength of 6000 kg/cm.sup.2, a tensile strength of 500 kg/cm.sup.2 and 0.01 elongation at room temperature, which constitutes a 5-10 -fold increase, as compared with the corresponding characteristics of the known granular materials of a similar composition.
