Potassium
Potassium (CAS 7440-09-7, Formula K, Molar Mass 39.10) is a highly reactive alkali metal supplied by Tech Serve Solutions as chunks in mineral oil. With an assay of 99.5% trace metals basis, it is primarily utilised in chemical synthesis and materials science. Its low melting point and high reactivity make it a key element in various reduction processes and specialised metal applications. TSS offers this product for research and industrial applications.
Chemical Synthesis
Potassium serves as a powerful reducing agent in organic and inorganic synthesis. Its high electropositivity allows it to donate electrons readily, facilitating numerous chemical transformations.
Materials Science
This alkali metal can be used in the development of new materials, including alloys and intermetallic compounds. For example, it combines with silver to form K₂Ag and K₃Ag.
Reduction Processes
Due to its strong reducing capabilities, potassium is employed in specific industrial reduction processes where other agents may be insufficient.
