Protective coatings and coating compositions
摘要:
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.
