As a leading China Black Carborundum Manufacturer, we recognize that Black Silicon Carbide (SiC), commonly known as Black Carborundum, is no longer just a traditional abrasive. In the era of high-precision engineering and semiconductor advancement, its role has expanded into a critical industrial catalyst. This whitepaper explores the macro-industrial shift toward high-purity synthetic crystalline compounds and the role of Shanghai Creative Advanced Materials Co., Ltd (SCA) in defining these standards.
Black Carborundum is produced through the electrochemical reaction of silica sand and petroleum coke in electric resistance furnaces at temperatures exceeding 2,200°C. With a Mohs hardness of 9.2, it stands just below diamond and boron carbide, making it indispensable for processing low-tensile strength materials such as non-ferrous metals, glass, stone, and cast iron. However, the modern "Information Gain" in this sector lies in its semiconductor properties and high thermal conductivity, which are now being leveraged in thermal management systems for 5G infrastructure and EV power modules.
Moving from traditional grit sizes (F12-F220) to sub-micron and nano-scale powders for precision polishing in the semiconductor wafer industry. We are pioneering pressureless sintering techniques to enhance structural density.
International buyers are shifting focus from "lowest cost" to "supply chain resilience and carbon compliance." Our factory integrates ESG standards to meet the green manufacturing requirements of EU and North American partners.
Providing integrated solutions for the metallurgy industry, specifically in deoxidation and alloying, where our SiC variants reduce energy consumption by up to 15% during furnace operations.
Founded in the Shanghai Industrial Comprehensive Development Zone, we are a high-tech company that integrates R&D, production, and sales. Our core expertise lies in semiconductor ceramic targets, powder metallurgy, and advanced ceramic components.
With 19 years of industry experience, we have transitioned from a local manufacturer to a global leader in neutron absorption materials and high-purity ceramic powders.

One of the hardest man-made materials. Essential for individual soldier protection, tank armor, and neutron absorption in nuclear reactors. Second only to diamond in hardness.
Superior thermal shock resistance and high-temperature strength. Used in semiconductor precision components, LED thermal management, and refractory linings.
The standard for technical ceramics. Exceptional electrical insulation and corrosion resistance for chemical processing and aerospace components.
The next decade will see Black Carborundum playing a pivotal role in the "Green Transition." As global industries strive for carbon neutrality, the efficiency of SiC-based components in power electronics will reduce energy waste significantly. At SCA, our technical roadmap includes the development of Recycled Silicon Carbide systems, allowing for a circular economy in the abrasives market without sacrificing material purity.
We provide comprehensive compliance assurance for international markets, including REACH, RoHS, and ISO 9001:2015 certifications. Our localized support teams in major industrial hubs ensure that technical queries regarding material compatibility and thermal expansion coefficients are answered within 24 hours.
Q: What is the difference between Black Carborundum and Green Silicon Carbide?
A: Black Carborundum contains approximately 95% to 98% SiC, providing higher toughness but slightly lower purity than Green SiC. It is ideal for grinding low-tensile strength materials, whereas Green SiC (99%+) is used for hard alloys and optical glass.
Q: Can you customize the grit size for specific industrial applications?
A: Yes, we offer customization according to FEPA, JIS, and ANSI standards, ranging from coarse grits for sandblasting to ultra-fine powders for precision semiconductor polishing.
Q: How does SCA ensure the consistency of batch-to-batch production?
A: We utilize a proprietary "Fingerprint Analysis" for raw material sourcing and automated sintering controls that record over 50 variables per batch, ensuring 99.9% repeatability.
