NASA Building Massively Heat-Resistant Chips - Slashdot
Silicon carbide (SiC) chips can operate at 600 degrees Celsius or 1,112 degrees Fahrenheit where conventional silicon-based electronics — limited to about 350 C — would fail. The new silicon carbide differential amplifier integrated circuit chip may provide benefits to anything requiring long-lasting electronic circuits in very hot environments such as jets, spacecraft, and industrial
The thermal conductivity of silicon | Electronics Cooling
For steady state thermal analyses at the board and system level, however, accurate values are not required, because the influence of the Silicon on the overall performance is limited. Remarkably, the thermal conductivity (in W/mK) defined in various papers and handbooks varies widely – 68.8, 83.7, 100, 125, 140, 153.46!, 157 – and often only one value at an unknown temperature is recommended.
Boiling chips | Distillation | Solubility
Boiling chips are made of glass or porcelain small pieces. They are stable at temperature where distillation occurs, so will not contaminate the distilling substances and stay on the distilling flask. Of course one must use appropriate boiling chips not breakable
Semiconductor device - Wiki
Semiconductor conductivity can be controlled by the introduction of an electric or magnetic field, by exposure to light or heat, or by the mechanical deformation of a doped monocrystalline silicon grid; thus, semiconductors can make excellent sensors.
