Boron Carbide is common ceramic material with outstanding mechanical properties and thermal stability. With the superb properties, Boron carbide is applied for high temperature applications such as turbine, fusion reactor, heat exchanger, and concentrated solar power. With those high-capable applications, the process to fabricate this kind of ceramic is interesting to investigate. The modification is done to know the behavior in fabricating Boron Carbide in the most effective way. The particle size, types of oxide additives, and modifying sintering process are continuous variable to be developed
