Oni Assistant | Aluminum Ore
Thermal conductivity is how quickly heat moves through the element as a medium. You would want low conductivity when insulating your base, but high conductivity when transferring heat to be deleted. Heat capacity is how much energy is required to raise the temperature of the element by 1 degree. Some elements like water need lots of energy to be heated, others like metals, need much less.
High-alumina stone | Britannica
Other articles where High-alumina stone is discussed: refractory: High alumina: High-alumina refractories are made from bauxite, a naturally occurring material containing aluminum hydroxide (Al[OH]3) and kaolinitic clays. These raw materials are roasted to produce a mixture of synthetic alumina and mullite (an aluminosilicate mineral with the stone formula 3Al2O3 · 2SiO2).
Proppant Technologies | CARBO
No existing conventional proppant could provide the required conductivity at the anticipated 15,000 psi (and higher) prevailing closure stress. To meet these challenges a new proppant was developed, with the goal of achieving twice the baseline conductivity of any conventional proppant at 20,000 psi.
Metal - Wikipedia
The thermal conductivity of metals is useful for containers to heat materials over a flame. Metals are also used for heat sinks to protect sensitive equipment from overheating. The high reflectivity of some metals enables their use in mirrors, including precision astronomical instruments, and adds to the aesthetics of metallic jewelry.
