High-Purity Salts

halide (chloride) salts displaying an array of color in part due to the oxidation state of the associated metals

We provide a broad spectrum of high-purity salts, both anhydrous and hydrated, ranging from 99.9% to 99.999% purity as measured by inductively coupled plasma mass spectrometry (ICP-MS) or inductively coupled plasma optical emission spectrometry (ICP-OES). Our comprehensive salt portfolio includes:

  • Metal salts
  • Alkali salts
  • Alkaline metal salts
  • Precious metal salts
  • Rare earth salts
  • Halide salts
  • Acid salts

Typically, these high-purity ionic compounds are utilized as salt precursors in demanding solid state synthesis processes, such as sol-gel, co-precipitation, and precursor methods, as well as in precision nanoparticle synthesis for chemical reduction and solvothermal methods. Our premium salts can be used as catalysts in chemical synthesis and in electrolyte solutions for lithium-ion battery components.

Ultra-High Purity Salts

High-purity materials are crucial in research, development, and the production of advanced technologies that require premium properties, performance, and quality. We offer ultra-high purity salts with purity exceeding 99.998% (less than 10 parts per million trace metal impurities). Our ISO 9001 quality management system ensures high batch-to-batch consistency with available batch-specific certificates of analysis (CoA) for dependable and reliable performance.

AnhydroBeads™​ Salts

Our AnhydroBeads™ salts provide superior performance in air- and moisture-sensitive applications due to their high-purity, monodisperse, and free-flowing properties. These anhydrous salts are developed and tested under stringent dry manufacturing conditions to ensure water content at the parts-per-million scale, trace metal purity of 99.9% (3N) to 99.999% (5N), and low surface area-to-volume ratio (~2 mm in diameter).

Keep your work flowing with AnhydroBeads™ salts!

  • Reduced uptake rate of environmental moisture minimizes caking, dusting, and static buildup for repeated easy handling
  • Higher crucible packing densities and lower volatility in high-temperature solid state procedures
  • Easier pneumatic loading of salts to sample chambers due to less clogging issues associated with powdered salt counterparts
