During firing of resistor materials the resistance is influenced by gaseous contaminants and by compounds given off by other pastes. Nearly all inorganic salts which are slightly volatile at the firing temperature, and some rather stable organic materials influence the resistor properties. Halogenated materials are the most important and the higher ohmic series the most sensitive.

For aluminium conductors a very high sensitivity to fluorinated and chlorinated compounds has been found but in this case organic compounds have no influence.
