Is anyone here familiar with the speed of a temperature wave through Si02 or other electrical insulators?
Thanks,

simple_logic said:Bill, you are correct, the question should be rephrased as:
Is anyone here familiar with the speed of temperature diffusion through Si02 or other electrical insulators?
Did you even bother to read this article? It derives heat conduction in a relativistic framework and shows that conduction speeds are finite (and slow compared to the speed of light).simple_logic said:Is anyone here is familiar with the speed of temperature diffusion through any electrical insulators?
For those unfamiliar with the subject, Heat propagates at relativistic speeds1

The speed of heat conduction through glass depends on various factors such as the type of glass, its thickness, and the temperature difference between the two sides of the glass. Generally, the speed of heat conduction through glass ranges from 0.8 to 1.5 millimeters per second.
The type of glass greatly affects the speed of heat conduction. For example, borosilicate glass has a lower thermal conductivity compared to soda-lime glass, which means it conducts heat at a slower speed. This is because borosilicate glass contains more silica, which has a lower thermal conductivity compared to other components in glass.
Yes, the thickness of glass does affect the speed of heat conduction. Thicker glass has a slower rate of heat conduction compared to thinner glass. This is because thicker glass has a higher resistance to heat flow, which means it takes longer for the heat to pass through it.
The speed of heat conduction increases as the temperature difference between the two sides of the glass increases. This is because a greater temperature difference creates a stronger driving force for heat to flow from the hotter side to the colder side.
Yes, the speed of heat conduction through glass can be affected by external factors such as humidity, wind, and surrounding temperature. These factors can alter the temperature difference between the two sides of the glass, thus affecting the speed of heat conduction.
