WebThermal expansion. The thermal expansion of α-SiC is nearly linear over a wide range of temperature. The expansivity is 4.5×10 −6 C −1 from 20 °C to 1000 °C and 5.5×10 −6 °C −1 from 20 °C to 1500 °C. This is lower than the expansivity for refractory oxides and much lower than most metals. Specific heat. WebWhy Mercury is a Great Thermometer Filling. Mercury is an ideal thermometer filling for 5 reasons: 1. Mercury is a liquid from -39 ºC to 357 ºC. Few materials can be liquid in a similar range–and mercury is the only pure metal that is liquid at room temperature. Many of the other benefits I list would apply to most metals, but being a solid ...
