<p>PURPOSE:To obtain glass having a uniform film thickness and uniform physical properties by hydrolyzing metallic alcoholate contg. silicon alkoxide as a principal component in the presence of water or an org. solvent after adding a viscosity regulator so as to regulate the viscosity of the resulting soln. to the desired value. CONSTITUTION:To silicon alkoxide is added metallic alcoholate of Ti, Zr or the like, and to this added alcoholate are added a viscosity regulator having a superior thickening effect such as aqueous cellulose ether and water or an org. solvent such as methanol. By agitating them, the alcoholate is hydrolyzed to prepare a viscous soln. with about 5-30cps viscosity. By this viscosity regulation molded glass products having various shapes such as separate films, fibers, substrate coating and lump glass can be obtd.</p> |
