RESISTIVE COMPOUND MATERIAL Russian patent published in 1994 - IPC

FIELD: electrical engineering, chemical technology. SUBSTANCE: compound mixture has 5-20 mass % units of dispersed carbon for technical using, 35-50 units of portland cement, 40-60 mass % units of dielectric filling, sulfurized naphthalinformaldehyde oligomer 0,35-1,5 and water. So made compound provides higher density and uniformity of mixture, good overall strength, acceptable resistor power dissipation and reproducible specific electric resistivity of material. EFFECT: better electrical, physical and mechanical properties of resistors, electric heating elements and grounding devices. 1 tb
