摘要：

The stability of colloidal graphite dispersions was investigated. A mixed 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, ultramicroscopy and scanning electron microscopy were carried out to determine the size of the particles. Adherent films were obtained by spraying the dispersions onto glass plates. The 20 mum thick films had an electrical resistance within the 20-40 OMEGA cm-1 range. They proved to be suitable for spray application onto the exernal glass cone of cathode ray tubes.
