The landscape of industrial chemistry has shifted dramatically toward high-purity inorganic metal salts. Among these, copper nitrate and silver nitrate represent critical baseline chemicals for catalyst formulation, semiconductor metallization, and electroplating. As international demand climbs for high-efficiency solar cells and specialized electronics, factories in China are upgrading synthesis routes to eliminate trace elemental impurities (such as iron, lead, and free acid residuals).
At Yanxatech System Industries Limited (YANXA), starting from a fledgling small business unit in 2008, we have systematically aligned our synthesis partnerships with the highest requirements of modern metallurgy and organic chemistry. By engineering controlled crystallization protocols, Chinese manufacturers are now capable of exporting electronic-grade raw materials that compete directly with legacy Western suppliers at structured price levels.
Ensuring heavy metals remain under 5 ppm to prevent interference in chemical vapor deposition and mirror-coating reactions.
Adjusting crystalline structures for optimized surface area contact in oxidation-reduction processes.
Ensuring continuous raw material pipelines through deep collaborations with primary Chinese refiners.
Procurement offices in Europe and North America are actively implementing dual-sourcing strategies. By integrating vetted Chinese producers with ISO 9001 certifications, firms secure resilience against regional feedstock constraints.
Whether sourcing dry crystalline powder or pre-stabilized solutions, buyers expect precise stoichiometry. Modern factories support customization of physical properties, including grain sizing and bulk density.
Regulatory audits require clear tracing of heavy metal raw materials. Under YANXA’s compliance protocols, manufacturing facilities prioritize zero-waste water run-offs and responsible metal extraction loops.
Pure raw copper anodes or silver bullion are reacted under precise thermal control with nitric acid, ensuring complete oxidation and minimal residual gas emission.
Through multi-stage cooling loops, silver nitrate and copper nitrate are crystallized selectively to separate trace impurities, maximizing analytical assay values.
Products are packaged in light-shielded, moisture-barrier containers under cleanroom conditions to prevent premature photolytic reduction.
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℃, freezing point -118℃, 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 foul odor. Formalin readily vaporizes, releasing formaldehyde gas. Its boiling point is 96℃, relative density is 0.815/-20℃, and flash point is 55℃.
Product Overview: Hexamethylenetetramine, also known as hexamine or HMTA, is a white crystalline powder produced by the condensation reaction of formaldehyde and ammonia. It is a versatile organic chemical intermediate widely used in industrial manufacturing, pharmaceutical synthesis, rubber processing, and analytical chemistry.
Product Features: A white powdery solid with a flammable odor of formaldehyde. It is a linear polymer of formaldehyde with no fixed melting point.

Engineered utilizing high-pressure gas atomization technologies under inert atmosphere cover. This material achieves uniform alloy distribution, spherical morphology, high active metal index, and controlled particle size distributions required for aerospace, pyrotechnics, and industrial energetic material formulations.
Quality, safety, and efficiency prevail over all values in our business operations. We care about our customers' need for general chemical products as well as their unique, specific requirements for newly developed applications in a timely manner.
Chemical business activities expose more safety and health concerns than other industrial sectors. We strictly adhere to technical requirements and execute all chemical handling in a safe way to ensure the protection of human health and the environment.
Cooperating with leading manufacturers and renowned research institutes in the field of specialty chemicals in China, YANXA is fully capable of supplying:
Our prices are subject to change depending on supply, metal raw exchange indexes (LME/Kitco), and other macroeconomic 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 appropriate for marine or specialized container routes. If you are looking to purchase smaller development quantities, please contact our team to discuss localized distributor inventory availability.
Yes, we can provide the majority of requested documentations, including Certificates of Analysis / Conformance (COA/COC); Hazard classification reports, Origin documentation, and standard export bills.
For standard samples, the lead time is approximately 7 days. For mass production and bulk shipments, the lead time is 20-30 days after receiving deposit payments. These timelines become effective upon our receipt of deposit and final approval of specifications.
You can complete payments directly to our bank account: 30% advance deposit, with the remaining 70% balance payable against the copy of the B/L by T/T or L/C at sight.
We warrant both the composition of our materials and our workmanship. Our fundamental commitment is client satisfaction. We handle quality inquiries through root-cause analysis in coordination with our quality control laboratory.
Yes, we strictly utilize high-quality export packaging. For dangerous goods (like class 5.1 oxidizers, including nitrates), we utilize UN-certified heavy-gauge drums. Cold-storage shippers or specialized liners are integrated for temperature-sensitive liquid rubbers.
