Corrugated metal seals

All these mica materials exhibit a uniform dielectric constant along with high resistivity. Usually, primary leak paths in compressed mica seals are the interfaces between mica sealants and the ceramic/metal component. Hgure 5.6a shows the gas-light seal formed by mica crystals and the predominant leakage routes. To improve the performance of mica seals, mica powder can be placed inside the gaps in corrugated metal seals O ig. 5.6b). 

The setup is largely comprised of a continuous-flow, compensating calorimeter which consists of a flooded measuring kettle housed in an intermediate thermostat, which is enveloped by a base thermostat. The base thermostat and the intermediate thermostat are filled with a thermostat liquid. The base thermostat, the intermediate thermostat and the flow measuring kettle are each provided with a mixer, baffles and temperature sensors. The mixer of the base and intermediate thermostats are classic stirrers, and the mixer in the flooded measuring kettle is a circular pendulum mixer. Its bearing is protected from contamination with the reaction mixture by corrugated metal bellows, which is joined to the cover of the shaft to form a seal.
