CORROSION COMMENTARY

FUTURE FOR MOLYBDATES. Results reported from the Battelle Memorial Institute suggest that molybdates may have a future as anti‐corrosive pigments. Two advantages over conventional materials such as red lead, zinc chromate and iron oxide are their non‐toxicity and white colour. They are, however, more expensive, especially when compared on a weight basis, but the difference in cost is less marked when compared on a volume basis, the molybdates being lower in density than the conventional pigments.
