Abstract:
    The driving device for calorimeter consists of three parts: rotating shaft, shaft sleeve and stopping ring. The making process includes the steps of fining treatment of silicon nitride material, forming, pneumatic sintering and fine processing. The driving device made of silicon nitride may be used in boiling water and water vapor at 100 deg.c for long period, and has less wear and high corrosion resistance. The calorimeter with the driving device may be used in boiling water and water vapor for long period for precise heat metering.
