Tantalum carbide is widely used as sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable material for aircrafts and rockets in aerospace
Silicon carbide is non-oxide ceramic with properties like high hardness and strength, high melting point, thermal and chemical stability, oxidation resistance, high erosion resistance. Figure 2.5. The Silicon Carbide (SiC) material structure.
Silicon carbide’s strength, hardness, durability, corrosion resistance, and high melting point also allow it to be used in extreme and high-performance engineering appliions. Pump bearings, valves, sandblasting injectors, extrusion dies, and heating elements are just some of the components typically constructed from SiC.
