The thermal conductivity of sand is ~0.25 [W/(m K)]. The thermal conductivity of silicon carbide is 120 [W/(m K)]. A huge difference. For comparisons sake, aluminum is 237. That should solve the slow heating and cooling problem. A potential drawback to
Gallium oxide devices can be very small and thin, so you can use very effective thermal management, even though the thermal conductivity is so low. At the recent IEEE Workshop on Wide Bandgap Power Devices and Appliions, a paper given by a colleague of mine - Paul Paret from NREL in Golden, Colorado - showed thermal modelling of gallium oxide devices attached to a base plate.

Thermal Conductivity - k - is the quantity of heat transmitted due to an unit temperature gradient, in unit time under steady conditions in a direction normal to a surface of the unit area. Thermal Conductivity - k - is used in the Fourier''s equation. Calculate Conductive
The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.

Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. The thermal conductivity of a material is highly dependent on composition and structure. Generally sing, dense materials such as metals and stone are good conductors of heat, while low density substances such as gas and porous insulation are poor conductors of heat.
