ABSTRACT
The suspension of $Al_2O_3$ which has long-term stability was made by mechanical milling. Thin films were evaluated and made to use as coating materials. A particle size of the suspension manufactured was 98 nm when 2 mt% nitric acid was added. It indicated that viscosity of the suspension is 12 cps and that it had the long-term stability. Thickness which was from 200 nm to 600 nm of the thin films was able to be made by adjusting draw rate and organic additive. Cracks of thin films at room temperature were prevented by adding Ethyl cellulose from 0.5 wt% to 2 wt%. The thin film heated at $500^{circ}C$ indicated a hydrophilic property against water and an excellent permeability against a visible ray.
Key words: $Al_2O_3$, Alumina thin films, Ceramic coating
