Surface Coating and Coupling Treatment

In surface coating and coupling treatment, first the whisker surface is coated with a layer of inorganic substance, such as [Pg.123]

Coating silicon oxide film. Whiskers (10 wt%) are mixed with water and quickly dispersed. Sodium silicate, measured according to 5%-10% of coating content, is dissolved in water and added slowly into the whisker slurry with stirring. Then the pH is adjusted to 9.5 by slowly adding diluted sulfuric acid and the mixture is kept [Pg.124]

Furthermore, coating silicon oxide film also can be achieved by using the TEOS (tetraethylortho) sol-gel method. Aluminum borate (AlBw) whiskers are added to absolute ethyl alcohol and dispersed in an ultrasonic cleaner and then [Pg.124]
