Abstract
The stability of colloidal graphite dispersions was investigated. A mi xed stabilizer (CELAD) consisting of a non-ionic cellulose derivative and an anionic polymer was used to facilitate the grinding process and to stabilize the aqueous dispersions. Measurements of turbidity, ultr amicroscopy and scanning electron microscopy were carried out to deter mine the size of the particles. Adherent films were obtained by sprayi ng the dispersions onto glass plates. The 20 mum thick films had an el ectrical resistance within the 20-40 OMEGA cm-1 range. They proved to be suitable for spray application onto the exernal glass cone of catho de ray tubes.
