Yanxatech System Industries Limited (hereinafter referred to as YANXA) stands as a premier, fast-growing Chinese manufacturer and supplier of specialty materials. Founded in 2008, YANXA started as a dedicated development unit focused on advanced chemical materials and has steadily evolved into a global powerhouse in critical industrial chemical refining.
Over more than 15 years of industry presence, our mission remains grounded in delivering premium chemical solutions that power the automotive, pharmaceutical, electronic, and aerospace sectors. Working closely with top-tier research institutes, YANXA specializes in three primary high-performance product categories:
Bismuth Nitrate (typically presented as Bismuth Nitrate Pentahydrate, Bi(NO₃)₃·5H₂O) is a key inorganic metal oxide precursor. To secure reliable, cost-efficient, and pure outputs, global chemical enterprises leverage Chinese manufacturing assets that offer unmatched advantages in material processing.
Our raw manufacturing capabilities allow for customized crystallization stages, minimizing sodium, chloride, and sulfate impurities to fractions of a percent, meeting ACS and industrial specifications.
China holds the world's largest deposits of elemental Bismuth. By partnering with direct local factories, YANXA ensures raw materials availability even during periods of high market volatility.
We manage transport safety documents, specialized heavy-duty drum packaging, and temperature-controlled storage, preventing decay and maintaining safe shipment standards.
| Analytical Parameter | Standard Grade Specification | High-Purity Catalyst Grade | Methodology / Verification |
|---|---|---|---|
| Assay (as Bi(NO₃)₃·5H₂O) | ≥ 98.0% | ≥ 99.5% | Complexometric Titration |
| Insoluble in Dilute Nitric Acid | ≤ 0.05% | ≤ 0.01% | Gravimetric Analysis |
| Chloride (Cl) | ≤ 0.005% | ≤ 0.001% | Turbidimetry |
| Sulfate (SO₄) | ≤ 0.01% | ≤ 0.005% | Turbidimetry |
| Heavy Metals (as Pb/Cu) | ≤ 0.02% | ≤ 0.002% | ICP-OES / AAS |
Operating as a modern chemical supplier demands more than basic manufacturing. Regulatory compliance, packaging verification, and environmental sustainability act as foundational pillars for YANXA's operational footprint.
We guarantee compliance with regional registration schemas (including REACH for the European Union, GHS labeling guidelines, and OSHA regulations). All documents, including COA, MSDS, and Customs Declarations, are customized for local regulatory requirements.
Bismuth Nitrate behaves as a strong oxidizer. We utilize UN-certified composite fiber drums with double-sealed moisture-resistant polyethylene liners. We coordinate with specialized logistics networks to handle Class 5.1 dangerous goods, guaranteeing incident-free customs clearance and delivery.
Our collaborative production sites utilize automated wastewater treatment systems and zero-emission closed-loop gas capture. This helps maintain standard chemical properties while minimizing environmental impacts.
Understanding that applications require distinct crystalline sizes, YANXA provides customizable crystallization sizes and tailored packaging sizes, ranging from 25kg industrial bags to large bulk packaging options.
In addition to Bismuth Nitrate, YANXA collaborates with leading manufacturers and renowned research institutes across China to offer a complete range of industrial chemical intermediates, synthetic rubber resins, and metal alloys.
Product Characteristics: Formaldehyde is a colorless, volatile liquid that polymerizes easily and is highly soluble in water, alcohol, and ether. It acts as a strong reducing agent and oxidizes to formic acid upon exposure to air. The commercial product is supplied as formalin, a 37-50% formaldehyde solution containing small quantities of methanol as a polymerization inhibitor. The solution exhibits a milky-white appearance and a sharp, characteristic odor. It vaporizes easily to release gaseous formaldehyde.
Product Overview: Hexamethylenetetramine, also widely known as Hexamine or HMTA, is a white crystalline powder synthesized by the condensation reaction of formaldehyde and ammonia. It is a highly versatile organic chemical intermediate. It is heavily utilized in phenolic resin production, pharmaceutical synthesis, vulcanization acceleration in rubber processing, and as a component in stabilizer formulations.
Product Features: A white, flammable crystalline powder with a characteristic odor of formaldehyde. It serves as a linear polymer of formaldehyde without a fixed melting point, depolymerizing to release formaldehyde gas upon heating. Highly suitable for coating resins, adhesives, and organic synthesis where water-free environments are required.
| Item Specification | Premium Grade | Industrial Grade |
|---|---|---|
| Content (Purity) | ≥ 96.0% | ≥ 92.0% |
| Solubility | ≤ 40 minutes | ≤ 40 minutes |
| Formic Acid Content | ≤ 0.05% | ≤ 0.05% |
| pH Level | 5.0 - 7.0 | 5.0 - 7.0 |
Bismuth Nitrate plays a critical role as an intermediate across high-tech manufacturing, pharmaceutical products, and advanced catalyst structures.
Used to synthesize active pharmaceutical ingredients (APIs), including bismuth subsalicylate and bismuth subnitrate for gastrointestinal treatments. Its high radiopacity also makes it valuable in specialized diagnostic imaging compounds.
Acts as a highly selective catalyst in organic synthesis reactions, including selective oxidations and carbon-carbon bond forming processes. It is a preferred alternative to more toxic heavy metal catalyst systems.
Acts as a key precursor in producing bismuth vanadate (BiVO₄), a high-performance non-toxic yellow pigment. It is also used in manufacturing functional ceramics and optical glass structures.
Quality, safety, and efficiency guide YANXA's operations. Chemicals present unique safety and environmental responsibilities. We ensure all activities are carried out safely, protecting human health and local ecosystems.
Our standard industrial-grade Bismuth Nitrate Pentahydrate assays at ≥98.0%. For specialized catalyst applications, we supply high-purity grades at ≥99.5% with strictly limited heavy metal and chloride impurities.
