High-precision components for semiconductor, aerospace, and metallurgy
High-Temperature Integrity Meets Chemical Inertness
In the realm of high-performance metallurgy, Boron Nitride (BN) crucibles are unparalleled. Unlike graphite or alumina, BN does not react with most molten metals, including aluminum, magnesium, and zinc alloys. This ensures zero contamination in sensitive semiconductor grade processing.
Boron Nitride possesses an extraordinary ability to withstand rapid temperature changes. Our crucibles can transition from room temperature to 1000°C in minutes without cracking, a critical requirement for R&D labs and automated manufacturing lines.
Acting as a high-temperature dielectric, BN crucibles provide excellent electrical insulation even at temperatures exceeding 2000°C in inert atmospheres. This makes them ideal for vacuum induction melting and MBE (Molecular Beam Epitaxy) processes.

Established in the Shanghai Industrial Comprehensive Development Zone, we are a high-tech powerhouse integrating R&D, production, and sales. Our core expertise spans semiconductor ceramic targets, powder metallurgy targets, and high-performance ceramic components.
The Evolution of Boron Nitride in Next-Gen Technology
As the industry moves toward 2nm and 3nm nodes, the requirement for ultra-high purity PBN (Pyrolytic Boron Nitride) crucibles has surged. The total absence of carbon and oxygen impurities is now the "gold standard" for compound semiconductor growth.
The rise of SiC (Silicon Carbide) power devices for EVs requires specialized sintering environments. BN crucibles are becoming the preferred container for high-temperature crystal growth due to their low-wetting properties.
Lightweight, heat-resistant components in hypersonic flight and rocket engines utilize BN ceramic composites. Manufacturers in China are now leading the way in large-scale geometric BN production.
Procurement heads from Fortune 500 companies now prioritize Full Record Traceability. At SCA, we provide serial numbers for every unit, tracking the journey from raw powder to the final sintered crucible. Our "Information Gain" approach ensures our partners receive not just a product, but a comprehensive technical dossier including thermal expansion coefficients and purity assays.

Technical Insights for Engineers & Procurement Officers
BN is an electrical insulator and does not react with carbon-sensitive melts. It also provides a cleaner vacuum environment as it does not outgas as much as graphite at high temperatures.
In an inert atmosphere (Argon/Nitrogen) or vacuum, our BN crucibles can safely operate up to 2000°C. In an oxidizing environment, they remain stable up to 900°C.
Yes. Our CNC machining department specializes in custom geometries including multi-bore crucibles, threaded components, and specialized lips for pouring applications.
We use ICP-OES and GDMS testing for every batch of raw powder. Our pyrolytic BN process involves chemical vapor deposition which inherently ensures 99.99% purity.
While BN is a ceramic, it has a "machinable" quality similar to graphite. We use customized shock-absorbent packaging and vacuum sealing to ensure zero-breakage global delivery.
