Abstract
A protective coating on a metal surface comprises a particulate material produced by a method including heating an animal skeletal material to a temperature of at least 1000° C. for a time sufficient to convert at least part of the calcium carbonate in the skeletal material to calcium oxide and produce a calcined product; and then contacting at least part of the calcined product with water to produce the particulate material containing calcium hydrate.
Claims6
A method of producing a protective coating on a metal surface, the method comprising:
- (a) heating an animal skeletal material to a temperature of at least 1000° C. to convert at least part of the calcium carbonate in the skeletal material to calcium oxide and produce a calcined product;
- (b) contacting at least part of said calcined product with water to produce a particulate material containing calcium hydrate;
- (c) dispersing said particulate material in a liquid carrier to produce a coating composition comprising said particulate material;
- and
- (d) applying said coating composition to a metal surface to produce a protective coating thereon.
