(WO9412447-A1)      A ceramic powder mixt. which sinters at temps. of about 1400 deg.C comprises (i) 1 mol. of LaCr1-xMx03, where M is a divalent metal selected from Zn, Cu or mixts. and x is 0.02-0.2; (ii) y mols. of B203, where y is 0.0005 to 0.04; and (iii) z mols. of La203, where z/y is 1.4-2.    Method for prepn. of the doped La chromite powder comprises: (a) preparing the La chromite precursor powder and Adsorbate, which is absorbed on the powder in an amt. of 35 wt.%, based on the total precursor wt. where the precursor is prepd. by: (i) reacting a soln. contg. a La cpd. and a Cr cpd. in an at. ratio of La:Cr of 1:1-x, with a stoichiometric excess of NH4OH to ppte. a hydroxide in the form of a slurry; (ii) washing the pptd. hydroxide with deionised water or DI water/alcohol mixts. to remove most of the anions from the La and Cr cpds. to yield a slurry in a water/alcohol liq.; (iii) adding to the slurry a soln. of an M cpd. to yield an atomic ratio of La:Cr:M of 1:1-x:x; (iv) sepg. the powder from the water/alcohol liq. at supercritical conditions, where temp. and pressure are equal to or greater than the critical point of the water/alcohol liq. in a batch or continuous process to obtain the precursor La chromite powder; (b) calcining the precursor at a temp. of 650-1100 deg.C for 0.5-4 hrs. followed by de-agglomeration to obtain sinter-reactive La chromite powder having the formula LaCr1-xMxO3; and (c) incorporating into the said powder z mols. of La203 and y mols. of B203, where y is 0.005-0.04 and z/y is 1-3.    USE/ADVANTAGE -   The present invention relates to a sinter-reactive La chromite ceramic for use as an interconnect material in a solid oxide fuel cell. The La chromite ceramic sinters at lower temps. than previous powders.
