Precision-engineered. Used in armors for military, law enforcement and defense.
Silicon carbide is expensive because it needs to be produced synthetically through high-temperature processes that are very sophisticated, and the powders have to be extremely pure and fine particle size. Its sintering is around 2000°C, and hence, energy and equipment costs are very high. Machining is difficult due to the hardness, and diamond cutting tools and specialized equipment have to be employed. The overall manufacturing is long with low yields and technical demands.
Silicon carbide is extremely hard, ranking about 9–9.5 on the Mohs hardness scale, just below diamond, which is rated 10. While it is not as hard as diamond, it is one of the hardest industrial materials available, offering excellent wear resistance and mechanical strength.
While companies like Saint-Gobain, 3M, and CoorsTek dominate the market, trusted suppliers like Newthink Material have built a strong reputation for offering reliable, high-performance silicon carbide products tailored to diverse industrial needs.
Yes, silicon carbide ceramic is used in bulletproof applications. Its combination of high hardness, light weight, and strong impact resistance makes it an ideal material for manufacturing ballistic armor plates used in military and law enforcement protection.
Silicon carbide ceramics have better thermal conductivity, mechanical strength, and resistance to high temperatures than alumina or zirconia.
Thermal conductivity in silicon carbide is 100-120 W/m·K, which is significantly higher than alumina, providing effective heat dissipation that is ideal for electronics and thermal management. The bending strength of SiC ceramic is 380 MPa at room temperature, which is remarkably good for maintaining strength while subject to high temperatures. This is what alumina and zirconia cannot provide.
In comparison to zirconia, silicon carbide is much more stable at high temperatures. Zirconia generally degrades above 750℃.
In its pure and dense state, SiC has very high resistivity, often over 1013 Ω·cm at room temperature and therefore can be considered an effective electrical insulator.
When doped with boron or aluminum, its resistivity decreases and then become semiconductive. In some composite materials like SiC30, in which about 30-35% graphite is added, the material remains highly thermally conductive, while also being electrically conductive.
Yes. But SiC requires specialized tooling and expertise because of its extreme hardness and brittleness. Only diamond grinding or CNC precision machining can shape SiC accurately enough, often holding tolerances down to ±0.002 mm. SiC can be polished to a mirror finish with surface roughness of Ra 0.01 µm.
