Silicon Carbide

About Silicon Carbide

Silicon Carbide (SiC) is a remarkable material known for its exceptional hardness and thermal properties. Naturally occurring as the rare mineral moissanite, the majority of SiC used in industrial applications is synthesized in laboratories and factories. Since the late 19th century, SiC has been mass-produced primarily as an abrasive due to its superior hardness. Depending on its purity, silicon carbide powder exhibits distinct colors: low-purity SiC appears black, while grades with purity exceeding 90% display a green hue.

Manufacturing and Applications

SiC grains are bonded through sintering to create high-performance ceramic materials. These ceramics are integral to various applications, including:

• Automotive Components: Such as car brakes, where durability and heat resistance are crucial.
• Ballistic Protection: Used in bulletproof materials for ballistic vests.
• Industrial Furnaces: SiC tubes serve as essential components in high-temperature environments.
• Thermocouple Protectors: Ensuring accurate temperature measurements in harsh conditions.
• Turbo Engines: Replacing traditional metal parts to enhance performance and longevity.

With the ability to withstand working temperatures of 2000°C or higher, silicon carbide is indispensable in environments that demand both resilience and thermal stability.

Purity and Industrial Use

While low-purity, cost-effective silicon carbide powder is extensively used in abrasives and cutting tools, high-purity SiC finds applications in advanced fields such as the semiconductor industry. The purity levels directly influence the material's color and suitability for specific applications, making quality control a critical aspect of SiC production.
