2. Glaze defects - Wikipedia

   en.wikipedia.org/wiki/Glaze_defects

   Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...

   The HRSI tile was composed of high purity silica fibers. Ninety percent of the volume of the tile was empty space, giving it a very low density (9 lb/cu ft or 140 kg/m 3) making it light enough for spaceflight. [1] The uncoated tiles were bright white in appearance and looked more like a solid ceramic than the foam-like material that they were.

7. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
