We coated slurry consisting of CdS, ZnS in the desired proportion—CdCl2 (as adhesive) and ethylene glycol (as binder)—onto the glass substrates. The films were sintered at a range of temperatures in air atmosphere for the optimization of sintering temperatures using reflection spectroscopy. It was noticed that below 500°C, CdS-dominated films were obtained, and above 500°C, ZnS-dominated films were obtained. The films of desired composition giving appropriate results are obtained at 500°C. The reason is easily understood through reflection spectroscopic studies. Thus, we found 500°C to be the optimum sintering temperature and 10 min was the proper sintering time.

Studies in ketonic resin / L. T. Gangotri in PAINTINDIA, Vol. LVI, N° 9 (09/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 9 (09/2006) . - p. 69-73 Titre : Studies in ketonic resin Type de document : texte imprimé Auteurs : L. T. Gangotri, Auteur ; V. Singh, Auteur ; R. S. Gour, Auteur Année de publication : 2006 Article en page(s) : p. 69-73 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Three different compositions were tried for the preparation of ketonic resin by changing the mole ratio of cyclohexanone and formaldehyde. 1:1 mole ratio was found to give excellent results. Ketonic resins of different softening points ranging from 72-112°C were prepared The reaction temperature was 60°C. The heat effect on the resin was also evaluated at 110°C, 150°C 200°C for 1,2 and 3 hours. The study showed that the softening point of the resin increased from 112°C to 170°C.
