INFLUENCE OF THE GRANULOMETRIC COMPOSITION OF POWDERS INGREDIENTS OF AN INORGANIC COMPOSITION AND THE ACIDITY OF PERMANENT BINDER OF RESISTIVE PASTE ON THE ELECTROPHYSICAL PROPERTIES OF THICK-FILM RESISTORS
The dependences of the specific surface resistance (ρS) of thick-film resistors on the specific surface of the conductive phase powders (Sc) and glasses of the U-1 and C-2 brands and their acid-base properties have been established.The difference in the behavior of the ρS - Sc functions for the selected glasses is due to the fact that Pb2Ru2O6 does not react with U-1 glass, but interacts with C-2 glass to form RuO2, which has a resistance significantly lower than that of Pb2Ru2O6. If the glass does not react with the conductive phase during the firing of the resistive paste, then the resistor ρS increases with an increase in the specific surface area of the inorganic ingredient powders. If the glass reacts with the conductive phase during the firing of the resistive paste to form a conductor with a lower resistance (high conductivity), then the ρS of the resistor does not increase as much and even decreases with an increase in the specific surface area of the powders of inorganic components.
