Cathode-ray tube is produced by firstly condensing and hydrolysing two or more alkyl silicate monomers in an alcohol soln. and in an average range of dimer to hexamer thereby forming, as a condensate, a soln. (I) contg. polyalkyl siloxane. Soln. (I) is then coated on a cathode-ray tube faceplate. The condensing reaction of soln. (I) is then continued to form a polyalkylsiloxane condensate (II). Finally, (II) is sintered to convert it to SiO2 by dehydration and dealcoholation reactions, thereby forming an SiO2 film on the faceplate.
