Abstract: A conductive material for use in interior coating of a cathode ray tube (CRT), which includes an aqueous dispersion medium containing potassium silicate and a dispersing agent; and graphite particles. The potassium silicate of the aqueous dispersion medium has a silicon dioxide (SiO2) to potassium oxide (K2O) mole ratio in the range of 4.5:1 to 6:1, and is prepared by adding hydrosilica gel to a potassium silicate aqueous solution having a SiO2 to K2O mole ratio less than 4.5:1.
