Hi
There are indeed published works on the physics behind thermistors. The
ones I’ve read (many decades ago …) didn’t say a lot about aging mechanisms
beyond the usual stuff you could guess at. Things like humidity can contaminate
the material, glass sealing is a good idea ( not a big surprise …
Here's a NIST paper on Thermistor stability:

Bruce Griffith points to the note put out by Littelfuse. It is very meagre. It
says that '...thermistors can be produced with typical drift of only 0.001˚C
to 0.002˚C per Year." It doesn't say that they are produced and still less that
Littelfuse produces them. Bruce also refers to thermistors
