Cadmium Nitrate Tetrahydrate [Cd(NO3)2·4H2O, CAS: 10022-68-1 / 10325-94-7] serves as an indispensable high-reactivity inorganic precursor across optoelectronics, specialized ceramics, advanced battery chemistry, and catalytic engineering.
Within the modern renewable energy transition, cadmium nitrate represents a vital soluble source for the chemical bath deposition (CBD) of cadmium sulfide (CdS) buffer layers on Cadmium Telluride (CdTe) and CIGS solar cells. The exceptional water solubility and rapid reaction kinetics ensure uniform nanometer-scale film formation with minimal pinholes.
Colloidal CdSe, CdS, and CdTe semiconductor nanocrystals (quantum dots) demand ultra-pure precursor salts. Cadmium II nitrate facilitates precise ligand exchange and organometallic reaction pathways, enabling tight emission linewidths, high photoluminescence quantum yield (PLQY), and narrow particle size distribution essential for displays and medical bio-imaging.
In specialty glass manufacturing and technical ceramics, Cadmium II Nitrate serves as an essential thermal flux and dopant. When calcined in controlled atmospheres, it forms stable cadmium titanates and cadmium stannates with unique dielectric properties. Furthermore, due to cadmium's high thermal neutron absorption cross-section, tailored cadmium compounds are utilized in radiation shielding materials.
Combining vertical zinc-cadmium metallurgical integration, closed-loop hydrometallurgical purification, and massive economies of scale, our manufacturing facilities deliver unmatched cost stability and purity consistency.
Cadmium is predominantly recovered as an associated byproduct during zinc smelting. China's world-leading zinc metallurgical industrial clusters provide our chemical synthesis units with immediate, uninterrupted access to 99.995% refined cadmium metal feedstock. This geographical proximity eliminates intermediate shipping premiums, buffers against international commodity spot fluctuations, and guarantees reliable multi-hundred metric ton production commitments.
By managing the chain from high-purity electrolytic cadmium ingestion to continuous nitric acid dissolution, our factories eliminate cross-contamination and ensure tight control over insoluble residues and trace metallic contaminants.
Operating chemical plants in compliance with modern stringent environmental mandates requires significant capital expenditure in pollution abatement. Our modern manufacturing bases operate under China's Level-A Environmental Standards, deploying closed-circuit vacuum crystallization, multi-effect evaporators (MEE), and automated acid fume scrubbers.
Water effluent is recycled back into the dissolution loop through ultrafiltration and ion-exchange polishing columns, resulting in zero toxic liquid discharge and protecting international purchasers from supply-chain interruptions caused by environmental compliance audits.
Using automated continuous oscillatory baffled crystallizers, our lines regulate cooling curves within ±0.2°C. This yields crystal cakes with homogeneous crystal habit, eliminating unevaporated mother liquor inclusion and delivering free-flowing prisms that avoid cake agglomeration during ocean voyages.
Every batch lot undergoes Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Atomic Absorption Spectroscopy (AAS). We benchmark over 28 elemental impurities—specifically targeting Cu, Pb, Fe, Ni, and Zn—guaranteeing compliance with semiconductor and analytical-grade expectations.
Strategically situated within dedicated chemical industrial parks near primary maritime deep-water hubs (Ningbo, Qingdao, Shanghai), our export operations facilitate expedited Dangerous Goods (DG) inspection, container freight station (CFS) packaging, and multimodal ISO tank / UN drum staging within 5 working days.

Used in photovoltaic module plants where cadmium nitrate reacts with thiourea in an alkaline aqueous medium (ammonium hydroxide) at 60°C to 80°C. The slow release of Cd²⁺ cations enables smooth epitaxial deposition of CdS thin films onto transparent conductive oxides (TCO), optimizing quantum efficiency in the 300–500 nm solar spectrum.
Specialty aerospace and defense fasteners utilize cadmium electroplating baths derived from cadmium nitrate or cadmium fluoroborate electrolytes. The nitrate counter-ion promotes high throwing power and low hydrogen embrittlement, protecting high-strength steel hardware operating in severe marine and saline aerospace environments.
Serves as a precursor for cadmium oxide (CdO) and cadmium titanate catalysts used in selective esterification, oxidative dehydrogenation, and high-performance synthetic polymer stabilization. The thermal decomposition of nitrate salts at 350°C leaves clean oxide crystal structures free of halogen residues.
