Description

The thermal conductivity of the gradient medium plays a very important part in the development of a calorimeter. It is a large factor in determining the sensitivity. The thermal conductivity apparatus was built primarily to find out why the measured sensitivities of the microcalorimeters were so much smaller than the calculated values. This question haa been resolved. The apparatus is now being used to study the thermal conductivity of Santocel, a granular insulating material produced by Monsanto Chemical Company. The Interesting fact is that though this material is in the solid phase it has a lower thermal conductivity than air. ... continued below

Description

The thermal conductivity of the gradient medium plays a very important part in the development of a calorimeter. It is a large factor in determining the sensitivity. The thermal conductivity apparatus was built primarily to find out why the measured sensitivities of the microcalorimeters were so much smaller than the calculated values. This question haa been resolved. The apparatus is now being used to study the thermal conductivity of Santocel, a granular insulating material produced by Monsanto Chemical Company. The Interesting fact is that though this material is in the solid phase it has a lower thermal conductivity than air. In a previous quarterly report approximate evidence was submitted to show that Santocel A has a lower conductivity than air at room temperatures. This result was worth verification, since this material would then prove useful in the construction of microcalorimeters. A verification is submitted in this report.
