Direct access to high-purity industrial compounds, liquid elastomers, and structural metal powders engineered to match standard international safety guidelines.
Ammonium oxalate monohydrate ($\text{(NH}_4)_2\text{C}_2\text{O}_4 \cdot \text{H}_2\text{O}$) serves as a vital precipitant and analytical reagent across various industrial domains, including metallurgy, electronics, and microchemical engineering. Achieving an "Ultrafine" particle size profile significantly alters its chemical kinetics, dissolution speed, and particle interaction behaviors. This whitepaper analyzes the physical-chemical dynamics that make ultrafine grades the superior choice for modern advanced materials manufacturing.
Compared to standard crystalline granules, ultrafine ammonium oxalate offers a drastically higher specific surface area (SSA). In processes such as the precipitation of rare earth elements or advanced electronics component production, standard reagents dissolve too slowly or unevenly, resulting in structural defects or impurities. Ultrafine particles (typically $D_{50} \le 10 \mu\text{m}$) guarantee rapid, stoichiometric reaction progress and incredibly uniform chemical distribution.
| Property Parameter | Standard Commercial Grade | Ultrafine Premium Grade | Analytical / Electronic Grade |
|---|---|---|---|
| Assay ($\text{(NH}_4)_2\text{C}_2\text{O}_4 \cdot \text{H}_2\text{O}$) | $\ge 99.0\%$ | $\ge 99.5\%$ | $\ge 99.8\%$ |
| Particle Size ($D_{50}$) | $150 - 500 \mu\text{m}$ | $\le 10 \mu\text{m}$ | $\le 5 \mu\text{m}$ |
| Iron (Fe) Impurity | $\le 0.005\%$ | $\le 0.001\%$ | $\le 0.0005\%$ |
| Chloride ($\text{Cl}^-$) | $\le 0.002\%$ | $\le 0.001\%$ | $\le 0.0005\%$ |
| Insoluble Matter in Water | $\le 0.05\%$ | $\le 0.01\%$ | $\le 0.005\%$ |
As advanced electronics, catalyst production, and rare-earth separation refine their processes globally, sourcing strategies for high-quality chemical intermediates must evolve. Supply chains require high purity consistency, dynamic shipping compliance, and reliable technical documentation.
For multinational procurement leads, securing a consistent supply chain of fine chemicals represents major business challenges. Yanxatech System Industries Limited addresses these key failure points:
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 area relating to the 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.
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 over all values in our business. We care about what our customers need for general products as well as their unique and specific requirements for newly developed applications in a timely manner. We adhere strictly to technical requirements and make deliveries in almost perfect conformity. Because chemical businesses expose more safety concerns than other industrial sectors, we undertake all activities involving chemicals in a safe way to ensure the safety of human health and the environment.
To sustain market leadership in specialized chemical sourcing, we constantly invest in synthesizing next-generation raw materials. The roadmap below indicates our milestones in process optimization and eco-friendly manufacturing.
Standard crystallization relies on mechanical stirring, which yields a wide particle size distribution. We are transitioning toward microfluidic channel precipitation. By regulating flow rates, we produce ultrafine ammonium oxalate with a D90 of under 8 microns directly during crystallization, removing the need for post-synthesis mechanical grinding and reducing impurity risks.
We are optimizing production cycles to capture and recycle ammonia gas by-products. This minimizes environmental emissions while ensuring we meet global ESG supply requirements mandated by top-tier electronics brands.
For chemical and pyrotechnic components, solid-state blending behavior is critical. Our future research focuses on surface-modified ultrafine crystals that flow smoothly under pneumatic industrial conveyors without caking.
We maintain strict quality control standards for our key products, supporting downstream applications worldwide.
Product Characteristics: Formaldehyde is a colorless liquid, easily polymerized, and readily soluble in water, alcohol, and ether. It is rapidly oxidized to formic acid in air, acting as a strong reducing agent. Its boiling point is -19°C, freezing point -118°C, and relative density to air is 1.067. Commercially, it is supplied in liquid form as formalin, a 37-50% formaldehyde solution with a small amount of methanol added as a polymerization inhibitor. The solution is milky white and has a strong odor. Formalin readily vaporizes, releasing formaldehyde gas. Its boiling point is 96°C, relative density is 0.815 at -20°C, and flash point is 55°C.

Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contacts us for further information.
Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website.
Yes, we can provide most documentation including Certificates of Analysis (COA) / Conformance; Insurance; Origin, and other export documents where required.
For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our proposed lead time does not work with your deadline, please talk to our sales manager to find a workable solution. In all cases, we will try to accommodate your needs.
You can make payments to our bank account: a 30% deposit in advance, and the remaining 70% balance against the copy of B/L by T/T or L/C at sight.

The shipping cost depends on the method you choose to receive the goods. Express is normally the quickest but also the most expensive way. Sea transportation is the best solution for large orders. Exact freight rates can be provided for reference only when we know the details of your order amount, weight, transportation method, etc. Please contact us for further information.
Ultrafine ammonium oxalate features a much smaller particle size (D50 under 10 microns). This creates a higher surface area, allowing it to dissolve much faster and react more uniformly. It is widely used as a high-efficiency precipitating agent in rare-earth refinement and electronic component manufacturing.
