<p>A method for the production of homogeneous coatings of a substance comprising at least two metals and/or metal compounds on a substrate, which method comprises depositing the substance from a gas or liquid phase from dinuclear or polynuclear mixed metal compounds via a four step process comprising heating the substance to 85-90% of a final temperature over a period of 5 to 20 minutes, reducing the temperature to a second temperature which is 2/3 of said final temperature, maintaining the second temperature for 11/2 to 21/2 hours, raising the second temperature over a period of 20 to 40 minutes, and maintaining the final temperature for 1 to 2 hours. The coated materials are, for example, useful for coating solar collectors with an alpha of at least 0.70 and an epsilon no greater than 0.30.</p> |
