500,000 tons dilute nitric acid & 300,000 tons concentrated nitric acid production capacity. Engineered via dual-pressure processes to deliver ultra-consistent chemical purity for downstream synthesis.
300,000 tons ammonium nitrate and specialized derivatives. Serving high-end industrial processing, energetic materials, and specialized synthesis pathways across international markets.
100,000 tons specialty formulas including high-purity inorganic salts, electronic-grade precursors, and custom compound matrices tailored to exacting enterprise buyer requirements.
Architecting sub-ppb and ppt-level chemical refinement pathways to support next-generation semiconductor fabrication nodes.
As the semiconductor industry advances toward 3nm and 2nm architectural nodes, the tolerance for trace metal impurities in process chemicals approaches zero. Electronic grade chemicals manufactured in China are subject to rigorous purity tiering. Yongchang Nitro Fertilizer’s R&D matrix aligns directly with SEMI (Semiconductor Equipment and Materials International) standards, deploying advanced distillation, ion-exchange purification, and sub-boiling rectification processes.

Real-time analytical verification down to parts-per-trillion (ppt) levels, guaranteeing absolute batch consistency prior to global dispatch.
Automated, non-contact bottling utilizing fluoropolymer (PFA/HDPE) containers pre-washed with ultra-pure water (UPW).
Thermal isolation purification preventing liquid splash carryover, resulting in pristine chemical clarity for delicate etching steps.
How China's leading chemical production capabilities power modern technology eco-systems worldwide.
High-purity nitric acid and specialized nitrate solutions act as crucial chemical agents during wet etching, wafer surface stripping, and RCA clean sequences. Eliminating organic residues and trace metallic contaminants is vital for yield optimization in advanced integrated circuit (IC) manufacturing.
In TFT-LCD, OLED, and Micro-LED glass substrate chemical processing, our high-precision metallic nitrates (Ferric Nitrate, Aluminum Nitrate) serve as ultra-consistent etchants and surface modifiers, delivering crisp circuit patterning without lateral undercut defects.
Massive scale photovoltaic manufacturing relies on cost-effective, high-volume process acids for silicon wafer texturization, junction isolation, and PSG removal. Our 500,000-ton capacity ensures uninterrupted supply pipelines for tier-1 solar module producers.
Molten salt grade sodium nitrate and potassium nitrate provide superior thermal energy storage (TES) capacity for concentrated solar power (CSP) stations and high-temperature industrial heat recycling, exhibiting outstanding thermal stability up to 550°C.
Precision chemical reagents such as Cobalt, Nickel, and Zinc nitrates form foundational building blocks for cathode precursor synthesis, enabling next-generation solid-state and high-energy-density ternary battery chemistries.
Specially modified nitrate salts and chemical formulations serve as essential polishing slurries and chemical toughening bath media for smartphone cover glass, high-aperture optical lenses, and aerospace viewing windows.

Embracing the "Dual-Circulation" development paradigm, Henan Yongchang Nitro Fertilizer is aggressively advancing its digital infrastructure:
With Chinese ingenuity at its core, Henan Yongchang is writing an Eastern legend on the global chemical map. We transcend borders with world-class quality and bridge continents through innovative solutions.
Stringent compliance protocols guaranteeing safe, seamless chemical logistics across borders.
For over five decades, we have accumulated extensive management expertise, developed a robust operational framework, and secured both domestic and international accreditations. Our logistics footprint connects Chinese manufacturing hubs to high-tech fab clusters worldwide.
Minimizing Total Cost of Ownership (TCO) through strategic OEM partnerships, security of supply, and direct manufacturer pricing.
In times of global supply chain volatility, sourcing directly from a primary synthesis manufacturer with 1M+ tons annual output eliminates intermediary markup and stockout risks. Henan Yongchang’s vertical control over ammonia-to-nitric-acid pathways ensures continuous plant operation even during global raw material crunches.
Chemical transport demands specialized containerization. We offer UN-rated ISO tank containers, 1000L IBC totes, and high-density fluoropolymer drums designed specifically for corrosive acids and oxidizers. Complete DG documentation, MSDS, and custom export customs clearance support are provided standard.
Off-the-shelf chemicals rarely meet niche industrial specifications. Our technical engineering team works hand-in-hand with customer R&D units to adjust concentration percentages, particle filtration levels, pH balances, and trace additive packages for bespoke production workflows.
Every single shipment is accompanied by a lot-specific Certificate of Analysis validated via ICP-MS, ion chromatography, and titrametric verification. Samples from each production run are archived in our QC library for 24 months to support longitudinal audit requirements.
Addressing core queries from procurement officers, chemical engineers, and international importers.
Direct manufacturer supply spanning industrial fertilizers, precursor salts, and electronic grade chemicals.
