Abstract
Abstract 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 α of at least 0.70 and an ε no greater than 0.30.

Total Claims: 18
Claim 1
Independent Claim
133 words
A method for the production of homogeneous coatings of a substance comprising at least two components selected from metals and metal compounds on a substrate comprising depositing said substance from a liquid phase from dinuclear or polynuclear mixed metal compounds by heating said dinuclear or polynuclear compounds to a first temperature about 85-90% of a final temperature over a period of about 5 to about 20 minutes, then heating at a second temperature about 62 to about 72% of said final temperature for about 11/2 to about 21/2 hours, then raising the temperature to the final temperature over about 20 to about 40 minutes and maintaining the final temperature for about 1 to about 2 hours, whereby said coating exhibits optical properties of at least 0.70 absorption and no greater than 0.30 emission.
Claim 2
Independent Claim
133 words
A method for the production of homogeneous coatings of a substance comprising at least two components selected from metals and metal compounds on a substrate comprising depositing said substance from a liquid phase from dinuclear or polynuclear mixed metal compounds by heating said dinuclear or polynuclear compounds to a first temperature about 85-90% of a final temperature over a period of about 5 to about 20 minutes, then heating at a second temperature about 62 to about 72% of said final temperature for about 11/2 to about 21/2 hours, then raising the temperature to the final temperature over about 20 to about 40 minutes and maintaining the final temperature for about 1 to about 2 hours, whereby said coating exhibits optical properties of at least 0.70 absorption and no greater than 0.30 emission.
