Many customers wonder: for hexagonal boron nitride (hBN) products, why do purity, dispersibility and stability vary widely among manufacturers? The key difference lies in production technology. With decades of experience in this industry, Dandong Chemical Research Institute has broken through the bottlenecks of traditional extensive production processes. Our self-developed integrated refined production process addresses common industry pain points and upgrades product quality.
Traditional boron material manufacturing mostly adopts extensive synthesis and relies on classification to control particle size, with many inherent shortcomings. Uneven synthesis temperature leads to broad particle size distribution and inconsistent crystallinity. Simplified purification results in high residual impurities and unstable purity. Particle size is adjusted by grading; products synthesized under off-target temperatures have poor crystallinity, abundant lattice defects and unstable performance. Such products fail to meet demanding requirements in manufacturing, semiconductor and other high-end applications.
Backed by technical accumulation from our provincial scientific research platform, we have independently developed a precise automatic temperature control system. Our one-step synthesis method produces target particle sizes and forms complete hexagonal crystal structures, delivering superior lubricity, thermal conductivity and electrical insulation. Rigorous post-treatment greatly reduces impurity content, achieving industry-leading purity. The one-step sintering synthesis yields uniform particle size distribution without mixed coarse/fine particles, suitable for coatings and ultra-thin forming.
Products made by traditional processes are only suitable for basic scenarios including general lubrication, conventional refractories and low-end coatings.
Products from our self-developed process feature stable performance and wide adaptability. They are widely applied in new energy, semiconductors, aerospace and other fields. Capable of replacing imported counterparts, our products offer better cost performance, flexible customization and timely after-sales support.
