摘要:
An improvement in producing an adherent metal oxide coating on a solid body comprises incorporating a nitrogen-containing polymer in a dispersion of the metal oxide into which the body is dipped. The pH of the dispersion is controlled in order to stabilize the dispersion. The body can then be dried. The invention is especially useful for applying a metal oxide coating to a ceramic material employed as a catalyst carrier for automotive exhaust gas purification.
