SUOYI Aluminum Nitride Powder Factory

 SUOYI Aluminum Nitride Powder Factory is the core production base of high-tech ceramic materials.
The aluminum nitride (AlN) powder factory is a modern industrial base focusing on the production of high-performance ceramic materials. It mainly produces high-purity, ultra-fine-grained aluminum nitride powder. Aluminum nitride is widely used in electronic packaging, semiconductor heat dissipation, LED substrates, high-temperature structural materials and other fields due to its excellent thermal conductivity, insulation and thermal expansion coefficient matching silicon. The factory provides key material support for the global high-tech industry through advanced production processes and strict quality control systems. Implement ISO 9001, IATF 16949 and other quality management systems, and some products meet ROHS and REACH environmental standards. Each batch of products will provide a test report, including chemical composition, particle size distribution, specific surface area and other data.
Aluminum nitride uses high-purity aluminum powder (purity ≥99.9%) and nitrogen as the main raw materials, and synthesizes aluminum nitride coarse powder by direct nitridation (aluminum powder reacts with nitrogen at high temperature to form AlN) or carbon thermal reduction (aluminum oxide reacts with carbon in nitrogen). Some high-end factories use plasma synthesis to prepare nano-scale powders.
The coarse powder is refined to submicron level (D50 ≤ 1μm) by airflow milling or ball milling equipment, and the particle size distribution is controlled by grading technology to ensure product consistency.
Impurities (such as free aluminum and oxygen content must be controlled at <1%) are removed by processes such as pickling and high-temperature deoxidation, and the purity of some products can reach more than 99.99%.
Packaging and storage of aluminum nitride
Moisture-proof and vacuum packaging is used in a dust-free environment to avoid moisture absorption of powder and performance degradation.
The automated production line is equipped with a PLC control system to achieve full process automation from synthesis to packaging.
Testing equipment X-ray diffractometer (XRD) analyzes crystal phase, laser particle size analyzer determines particle size, and thermal conductivity meter tests thermal conductivity (typical value ≥170 W/m·K).
Environmentally friendly design of waste gas treatment system.
