Yes, quartz has good thermal conductivity. According to the references provided, quartz has the highest thermal conductivity among all soil minerals, with a range of 7.7 – 8.4 W/m·K. This high thermal conductivity makes quartz suitable for applications where heat transfer is important.
Additionally, fused quartz, which is a type of quartz, possesses special properties that contribute to its thermal conductivity. These properties include a low degree of thermal expansion, elevated resistance to thermal shocks, a high softening temperature, and elevated thermal resistance. Fused quartz also has a high degree of transparency in the spectral range from violet to infrared, making it suitable for optical applications.
Furthermore, the references mention that quartz tubes can withstand high thermal shocks, ranging from 1000 degrees Celsius to room temperature. This is due to the extremely low coefficient of thermal expansion of quartz, which contributes to its thermal stability.
In comparison to other materials, such as SiC (silicon carbide), quartz exhibits good thermal conductivity. SiC is known for its high thermal conductivity and low thermal expansion, which contribute to its thermal shock resistance. The thermal conductivity of SiC ranges from 120-270 W/mK, while quartz has a thermal conductivity of 7.7 – 8.4 W/m·K. Although SiC has a higher thermal conductivity than quartz, quartz still has good thermal conductivity considering its unique properties and applications.
