Abstract: PROBLEM TO BE SOLVED: To obtain a pigment for a spectrum from red-yellow to orange free from toxic metals and producible with an economical method by calcining a homogenous mixture of bismuth oxide and vanadium oxide and leading to vanadic acid bismuth having a specific composition containing additionally phosphorous in the form of phosphoric acid bismuth. SOLUTION: A vanadic acid bismuth pigment additionally containing phosphorous in the form of phosphoric acid bismuth in an amount of 0-0.5wt.%, expressed by the formula (Bi4 V2 O11 )1-x .(BiVO4 )x (0 =62 (measurement angle 45 deg., standard light D65). The pigment is obtained e.g. by calcining a homogenous mixture of bismuth oxide and vanadium oxide at 600-900 deg.C for 2-12hr, slowly cooling to the ambient temperature tanking at least 6-20hr down to about 200 deg.C and subsequently pulverizing the product.
