Ceramics are durable, acid-resistant, and alkali-resistant. The conventional preparation method involves curing under thousand degree high temperatures. With the newest nanotechnology technique, one can directly render the ceramic coating onto the aluminum or other metallic materials, giving the metal surface ceramic characteristics.

        The coatings preparation method involves the conventional spray method. After a hundred degree low temperature curing, a very thin ceramic coating is obtained. The surface itself has high-hardness, good adhesive properties, and is very durable, corrosion-resistant, fireproof, and high-temperature-resistant. This new type of ceramic coating can be used on subway cars, the outer walls of metallic structures, stickless cookware, and electric irons, products that require properties other coating cannot provide.
