Earlier this month, Alfa Chemistry unveiled a new product line of colloidal materials for scientists engaged in relevant research providing customers across the globe with easy access to comprehensive colloidal materials, including: colloidal catalysts, colloidal nanoparticles, hydrocolloids, and colloidal silica.

“Colloids have unique electrical, optical, magnetic, and biological properties that large-scale materials do not possess, and therefore are widely used in the agriculture, biomedicine, energy, environment, and chemical industries,” said the Marketing Chief of Alfa Chemistry. “Established nearly 20 years ago, our Colloidal Materials Division is capable of developing and supplying a large number of flexible and innovative colloids.”

Colloidal Catalysts
Colloidal catalysts are advantageous in terms of their stability and recyclability. As an expert in catalysis, Alfa Chemistry has developed a number of catalytic synthesis technologies and can provide customers with a complete set of solutions, including special catalyst design, development, optimization, and improvement. Some colloidal catalysts provided by Alfa Chemistry involve aluminum sol, iron, palladium, platinum, rhodium, and other precious metal catalysts. To name just a few here: triphenylphosphine carbonyl rhodium chloride, 95%, tetrakis(triphenylphosphine)platinum, dichlorotetraamminepalladium, Pd: 43.0 wt.%, dichloro(pentamethylcyclopentadienyl)rhodium(III) dimer, allylpalladium chloride dimer, Pd: 58.2%, etc.

Colloidal Nanoparticles
Colloidal nanoparticles ( are a class of multifunctional materials, and Alfa Chemistry offers three categories of such materials: metal colloids, metal oxide colloids, and colloidal quantum dots. To name a few here, Barium Ferrite Slurry (BaFe12O19, Purity: 99.5%, Diameter: 80-100 nm), Bismuth Oxide Dispersion (Bi2O3, Diameter: 99.9%, diameter: 80 nm, solvent: propylene Glycol Monopropyl Ether); Nano silica water dispersion (SiO2, purity: >99.9%, diameter: 10 nm, 30 wt.%); Sodium-type silica sol, diameter: 78-82 nm, etc.
