摘要: A lanthanum chromite ceramic powder mixture that consists essentially of 1 mol of LaCr.sub.1-x M.sub.x O.sub.3, where M is a divalent metal selected from the group consisting of magnesium, calcium and mixtures thereof and x ranges from 0.03 to 0.3; y mols of B.sub.2 O.sub.3, where y ranges from 0.005 to 0.04; and z mols of La.sub.2 O.sub.3, where the ratio z/y ranges from 1.1 to 3. The mixture is formed into powder compacts and sintered to near full density at temperatures as low as 1400.degree. C.
