Thermal Diffusivity Data for Pyroceram 9606

Here is some data from testing I did using the LFA 457 and the reference sample pyroceram 9606.  Sheet one contains some data with notes, sheet 2 contains most of the data exported directly from the analysis software, and sheet 3 is a condensed version with just the results.

Square Sample Setup

When using any of the square sample holders, use the side length of the sample as the "diameter" when you input the measurement definitions. So far, I have seen no other sample holder listed in the measurement software except the Std SiC 10mm^2; I have therefore used this for 8x8 samples.

Based on what a representative of NETZCH showed us in screen snapshots, other LFA machines they manufacture include software that has options for 8x8 sample holders.  For some reason, the LFA 457 either does not have these other holders listed in the measurement software, or it is somehow hidden from plain sight.

Duration of an LFA Measurement

Yesterday's LFA analysis went from about12:45 pm to 4 pm. It consisted of measurements at 25C, 100C, and 200C (in this order); each temp had 5 shots.  I also noticed that it took 20-30 min to go from 100 C to 200 C.

Also, I coated an 8x8 sample with 4 coats/side, and the 10x10 sample with 1 coat/side.
