    摘要: A bismuth oxide/chromium oxide mixed phase pigment having the composition Bi.sub.2-x Cr.sub.x O.sub.3 wherein 0.05.times.0.5 and a specification surface of about 1.0 to 10 m.sup.2 /g is produced by mixing metallic bismuth intensively with a chromium (III) and/or chromium (VI) compound, calcining the homogeneous mixture in an oxidizing atmosphere at a temperature of about 500.degree. to 800.degree. C., and crushing the product to pigment size.
