SUOYI is a trustworthy manufacturer of boron nitride powder.

In today's rapidly developing new materials industry, boron nitride, with its excellent high-temperature resistance, chemical stability, lubrication properties, and electrical insulation characteristics, is widely used in high-tech fields such as aerospace, electronics, metallurgy, and chemicals, becoming one of the key functional materials. As a professional enterprise specializing in the research and development and production of boron nitride powder, SUOYI relies on its profound technical accumulation, rigorous quality management system, and comprehensive customer service mechanism to continuously provide customers in various industries with high-performance, high-reliability product solutions, gradually growing into a trustworthy industry partner.

SUOYI's core technology forges superior quality.

SUOYI uses high-purity boron and nitrogen sources as raw materials, combining advanced high-temperature synthesis processes and multi-stage precision purification technology to ensure that its boron nitride powder achieves industry-leading levels in purity, particle size distribution, and performance consistency. Its flagship product, hexagonal boron nitride powder (h-BN), has a graphite-like layered structure and is white and loose, hence its reputation as "white graphite." This material operates stably in an inert atmosphere up to 2000℃, has an oxidation resistance temperature exceeding 900℃, and maintains excellent lubrication performance even in extreme high-temperature environments, making it an ideal high-temperature solid lubricant.

Regarding purity control, SUOYI strictly implements full-process quality management to ensure that the boron nitride content is no less than 98.5%, while reducing impurities such as borates and iron to extremely low levels, guaranteeing the material's chemical stability and application reliability. Through nanoscale grinding and classification technology, products with different particle sizes from submicron to tens of micron can be flexibly provided to meet diverse process requirements such as thermal spraying, precision casting, and electronic packaging. Furthermore, the products possess a low dielectric constant (as low as 3.5) and ultra-high volume resistivity (exceeding 10¹⁶ Ω·cm), combined with excellent electrical insulation and high thermal conductivity, making them suitable for electronic devices with stringent requirements for heat dissipation and electrical safety.

SUOYI's comprehensive product matrix covers diverse needs.
SUOYI has built a boron nitride powder product system covering the needs of multiple industries, committed to providing customized material solutions. In the field of high-temperature lubrication, its powder can be used directly as a solid lubricant or incorporated into greases or coatings, significantly improving the wear resistance and service life of equipment under high-temperature and high-load conditions. In precision casting and glass processing, boron nitride, as a highly efficient mold release agent, can form a uniform lubricating layer on the mold surface, effectively preventing molten metal or glass from sticking to the mold, thus improving the surface quality of the finished product and production efficiency.

In the field of electronic information, SUOYI's boron nitride powder is a key raw material for preparing high thermal conductivity ceramic substrates and packaging materials. Its excellent thermal conductivity-insulation balance perfectly meets the stringent requirements of thermal management materials in cutting-edge fields such as 5G communication, power devices, and new energy vehicles. In the nuclear industry, thanks to boron nitride's excellent neutron absorption capacity, the product can be used in reactor structural materials and control rod assemblies, contributing to the safe and stable operation of nuclear facilities. Furthermore, as a high-performance filler, boron nitride can significantly improve the high-temperature resistance and corrosion resistance of polymer-based composite materials, and is widely used in high-end manufacturing scenarios such as aerospace structural components and lightweight automotive parts.

SUOYI's Strict Quality Control Ensures Stable Supply

SUOYI has established a comprehensive quality control system covering raw material procurement, production processes, and finished product delivery. At the raw material level, it collaborates with top global suppliers to conduct multi-dimensional testing of boron and nitrogen sources, ensuring high purity and consistency of initial materials. During production, automated production lines and real-time online monitoring systems are used to precisely control key parameters such as temperature, pressure, and reaction time, minimizing fluctuations caused by human intervention. At the finished product stage, each batch undergoes more than ten rigorous tests, including component analysis, particle size testing, and thermal stability assessment, ensuring all indicators meet standards before leaving the factory.

To meet the growing market demand, SUOYI continues to expand its production capacity. Its newly built modern production base is equipped with internationally advanced synthesis furnaces and purification equipment, significantly increasing annual production capacity and enabling it to handle large-scale orders. Simultaneously, the company has established a scientific inventory management mechanism, maintaining reasonable reserves of commonly used specifications to ensure timely delivery and stable supply.
