Compared with the ordinary thermally conductive ceramic sheet we used in the past, compared with the silicon carbide thermally conductive ceramic sheet, in terms of strength, the strength of the silicon carbide ceramic sheet is more than twice that of the ordinary one, and it can withstand high temperatures above 700 degrees Celsius. The emergence of the product has greatly promoted the development of automotive applications. For example, to reduce the fuel consumption of diesel engines by more than 30%, silicon carbide thermally conductive ceramic sheets are indispensable materials. In the current gasoline, about 80% of the combustion energy is lost in the heat transfer of heat energy, while the efficiency of the diesel engine is 33%. Therefore, using silicon carbide thermally conductive ceramic sheets with better thermal insulation performance for thermal insulation can greatly reduce the loss of this part, and then use waste turbochargers and power turbines to charge silicon carbide materials back and forth. Practice has proved that this can improve thermal efficiency. To 48%, the silicon carbide thermally conductive ceramic sheet makes it possible to quickly start the diesel engine. With this turbocharger, it has better heat resistance than today’s superalloys, but the specific gravity is only about one-third of the metal turbine. one.
