Abstract
A metal-ceramic composition, particularly for high temperature heat-transfer systems, consists of nickel through which is finely dispersed 5% by volume of Ni2Al2O4. The latter may be prepared by reacting equal molar ratios of NiO and Al2O3 at 2400 DEG F. for 2 hours, and is then ball-milled with carbonyl nickel of about 5 microns in a ceramic-lined mill containing alundum balls for twenty-four hours. The mixture is then compacted at 20 tons/ sq.inch and sintered in vacuum at 2400 DEG F. for four hours. The product may be cold-rolled into sheet, preferably with intermediate anneals at 1500 DEG F. in argon. A composition consisting of 8-10% by volume of Al2O3 dispersed in nickel is also referred to.
