if the temperature coefficient itself does not vary too much with temperature, a linear approximation will be useful in estimating the value "r" of a property at a temperature "t", given its value "r" at a reference temperature "t":









































where δ"t" is the difference between "t" and "t".









































for strongly temperature-dependent α, this approximation is only useful for small temperature differences δ"t".









































temperature coefficients are specified for various applications, including electric and magnetic properties of materials as well as reactivity. the temperature coefficient of most of the reactions lies between -2 & 3.

therefore, many materials that produce acceptable values of formula_5 include materials that have been alloyed or possess variable negative temperature coefficient (ntc), which occurs when a physical property (such as thermal conductivity or electrical resistivity) of a material lowers with increasing temperature, typically in a defined temperature range. for most materials, electrical resistivity will decrease with increasing temperature.









































materials with a negative temperature coefficient have been used in floor heating since 1971. the negative temperature coefficient avoids excessive local heating beneath carpets, bean bag chairs, mattresses, etc., which can damage wooden floors, and may infrequently cause fires.
