Abstract:

An improved dilatometer with a He cryostat was developed to increase the accuracy of dilatometric determinations below 77K. Only the investigated body is heated precautions are given as to how to avoid the temperature of the holder and holder stem from changing considerably during an experiment. The relative sensitivity for elongation is 1.6 x 10 to the minus 7th power, and the accuracy in the 30K range is plus or minus 5. Author
