High-Purity Salts

Petri dish with dynamic M created from high-purity salts

We offer a wide range of high-purity salts, including nitrates, oxalates, halides, sulfates, carbonates, and acetates, available in both anhydrous and hydrated forms. Purity levels range from 99.9% to 99.999%, as verified by inductively coupled plasma mass spectrometry (ICP-MS) or inductively coupled plasma optical emission spectrometry (ICP-OES). Our comprehensive salt portfolio includes:

Our high-purity ionic compounds serve as optimal salt precursors for various synthesis methods, including solid-state, sol-gel, and others such as hydrothermal and microwave-assisted techniques. They are ideal for synthesizing nanomaterials, composites, and inorganic complexes used in applications such as batteries, solar cells, catalysts, fuel cells, molten salt reactors, sensors, and more.

Ultra-High Purity Salts

Ultra-high-purity materials are vital for research, new technology development, and advanced product manufacturing, where superior performance and quality are essential. Our portfolio features salts with purity levels exceeding 99.998% and 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 reliable performance.

AnhydroBeads™​ Salts

Our AnhydroBeads™ salts deliver exceptional performance in air- and moisture-sensitive applications due to their high-purity, monodisperse, and free-flowing characteristics. 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 ranging from 99.9% (3N) to 99.999% (5N), and a low surface area-to-volume ratio (approximately 2 mm in diameter).

Features & Benefits

  • 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 fewer clogging issues associated with powdered salt counterparts
  • Low volatility for safe and stable use, storage, and transport

Redi-Dri™ Salts

Our Redi-Dri™ salts provide superior performance for moisture-sensitive applications due to their stringent specification testing and ease of handling. Our innovative packaging system prevents the absorption of environmental moisture by anhydrous and hydroscopic salts during transport and chemical storage, eliminating clumping and caking and preserving the compounds′ quality-assured, free-flowing properties.

Features & Benefits

  • Extended shelf life and free-flowing properties without anti-caking agents, reducing material waste
  • Slower absorption of environmental moisture
  • A safer, reusable alternative to single-use ampules
  • Faster dissolution of Redi-Dri™ salts reduces waiting time and enhances lab productivity

Catalysts

We offer a diverse selection of transition salts, rare earth salts, and precious metal salts used extensively as catalysts. These salts serve as coatings, catalyst precursors for PEM fuel cells, and effective homogeneous catalysts. Precious homogeneous catalysts, which fully dissolve in reaction mixtures, enable high yields under moderate conditions.

Whatever your need for organic or organometallic catalysis, we have the exact transition metal catalyst you're looking for.

Perovskite Solar Cells

The quality and durability of metal-halide perovskite solar cells are greatly influenced by the precursor materials and deposition methods used in the preparation of the perovskite layer. We offer high-purity salt precursors such as lead halides, tin halides, and cesium halides which are suitable for deposition methods due to their solubility in organic solvents.

Electroplating

We provide high-purity to ultra-high-purity salts for use as an electrolyte in the electroplating process. These salts serve as a source of metal ions, contributing to desirable characteristics such as electrical conductivity, optical appeal, and the creation of protective layers against corrosion, temperature, and mechanical stress.
