Direct wholesale access to our leading chemical compounds and industrial specialties engineered to exact global parameters.
Yanxatech System Industries Limited (hereinafter referred to as YANXA) is one of the growing suppliers in the field of specialty materials in China. Starting from a fledgling small business unit in 2008, YANXA is driven with the passion of developing a broad international market in the areas relating to chemical and mechanical industries.
Thanks to our team’s enduring and persistent work and our business partners’ long-lasting support, YANXA has steadily and vigorously grown into one company with excellence in delivering products and services relating to specialty chemicals. We cooperate with leading manufacturers and the renowned research institutes in the field of specialty chemicals in China.
Cooperating with leading manufacturers and the renowned research institutes in the field of specialty chemicals in China, YANXA is capable of supplying:
Quality, safety and efficiency prevail all the values in our business. We care what our customers' need on the general product as well as their unique and specific requirement.
Antimony powder (CAS Registry Number: 7440-36-0) is an essential element for metallurgical strengthening, chemical catalysts, and flame retardancy. YANXA provides pure and alloyed formats with customizable parameters.
Pure Antimony is a lustrous, silvery, bluish-white metalloid that is brittle and easily pulverized. When processed into powder form, its properties depend strongly on particle size distribution (PSD) and surface morphology. Through mechanical milling or chemical precipitation, we ensure precise control over:
We calibrate our manufacturing lines to supply various purity levels designed for specific industrial verticals. High-purity grades (4N/5N) are used predominantly in advanced optoelectronics, while 3N (99.9%) and alloyed grades serve the metallurgical and polymer-additive industries.
| Grade Designation | Purity (Sb Min %) | Typical Impurity Limits (Max ppm) | Key Applications |
|---|---|---|---|
| High Purity Electronic Grade (5N) | 99.999% | As: 2, Pb: 2, Fe: 1, Cu: 1, Bi: 1, S: 1 | Semiconductor dopant, thermoelectric materials, optoelectronic sensors. |
| Precision Chemical Grade (4N) | 99.99% | As: 10, Pb: 8, Fe: 5, Cu: 5, Bi: 5, Ni: 3 | Clarification agent in high-end optical glass, specialty alloy target manufacturing. |
| Metallurgical & Catalyst Grade (3N) | 99.9% | As: 100, Pb: 150, Fe: 50, Cu: 50, Bi: 80, S: 50 | PET polymerization catalysts, alloy strengthening agents, friction lining additives. |
| Flame Retardant Precursor | 99.5% | As: 250, Pb: 300, Fe: 100, Cu: 80, Bi: 100, S: 100 | Direct conversion to Antimony Trioxide ($Sb_2O_3$) for halogenated synergistic plastics. |
The evolution of Antimony applications is accelerating beyond traditional fire-retardant synergists. YANXA is investing in material refinements to power the future.
Antimony is emerging as a high-capacity anode material for sodium-ion and lithium-ion batteries. Alloyed antimony powder structures exhibit theoretical capacities exceeding 660 mAh/g, making them vital for grid-scale energy storage research.
Using chemical vapor deposition (CVD) and physical vapor deposition (PVD) techniques, our 5N ultra-pure Antimony powder is converted into metal targets for thin-film infrared detectors, phase-change memory devices, and photodetector arrays.
Traditional grids are being redesigned. Doping lead alloys with precise, ultra-fine antimony powder increases mechanical strength and prevents grid creep, extending the cycle life of telecom and automotive batteries under extreme operating temperatures.
In collaboration with China’s premier chemical engineering institutes, YANXA is refining mechanical milling procedures to produce monodisperse sub-micron antimony powders. These materials provide superior dispersion kinetics when blended into specialized polymer matrices.
How YANXA resolves complex engineering and manufacturing challenges across key global industrial sectors.
In electronics and automotive interior plastics, flammability regulations require robust performance. Our antimony powder serves as the ideal raw precursor for producing fine-particle Antimony Trioxide. When paired with halogenated flame retardants, it forms antimony trihalides in the gas phase. This process traps free radicals, quenching combustion reactions and lowering smoke emissions in critical public transit and aerospace components.
Heavy machinery bearings require low friction coefficients and high fatigue resistance. Adding YANXA Antimony powder to tin and lead matrices forms microscopic intermetallic compounds. These hard grains disperse within a softer metal matrix, creating classic Babbitt structures. This increases wear resistance in marine engines, turbines, and railway rolling stock.
The global industrial materials landscape demands a combination of raw material stability and agile processing. Through integrated refining operations in China, YANXA provides a secure supply chain with consistent quality controls.
Our partner facilities leverage automated chemical processing loops and real-time gas chromatography. This keeps raw mineral variations from affecting the final purity of our metal powders. Advanced dust-suppression and filtration technologies also ensure compliance with strict environmental mandates.
Continuous Operation Safeguards: By maintaining buffer stocks at central domestic hubs, we protect our clients from seasonal logistics bottlenecks and raw material volatility.

Shipping critical industrial chemical agents requires strict adherence to international safety frameworks.
Antimony powder is classified as a hazardous substance if inhaled or ingested. We enforce strict GHS classification labelling (Pictogram GHS07/GHS08) on all drums, boxes, and bulk super-sacks.
For European Union imports, we support registration dossiers and provide REACH declarations, alongside certifying RoHS compliance in electronic-grade formulations.
Depending on particle size and susceptibility to spontaneous combustion, we utilize UN-approved hazardous material packaging to prevent moisture exposure during transit.
Standardizing terms and expectations for high-volume trade partnerships.
To support commercial refining and manufacturing, YANXA maintains an ongoing Minimum Order Quantity (MOQ) policy for our international orders.
