Paper Title:
Hydrophobic Ceramic Surface by Sol-Gel Method
  Abstract

The sol-gel method was chosen in the experiment to make nano-structured coatings on the ceramics. In this experiment the TEOS, ETOH were chosen as the main reagents and the two group formulas whose scale were 3:50 and 18:25 were chosen to make the sol of silica by the way of sol-gel, and the two formula were mixed on some scale. The sols of the three formulas would be spread on the ceramics separately; and then burned in different temperatures of 500°C, 800°C, 900°C and 1000°C, last the samples were put into the 10% of trim ethyl chlorosilane of n-hexane solution to adorn the surface of spread the gel ceramics. The result of the samples, which are uncalcined, calcined and black and calcined and the surface adorned compared, shows that the contact angle of samples that have been calcined and the surface adorned becomes bigger. So the hydrophic effect is the best when there are all of the microstructure and the low-surface power on the ceramics surface.
