In what purities is potassium available?
The potassium product range extends from technical purities for industrial applications to high-purity grades for demanding research purposes. Potassium ingots are offered with a purity of 99.95% and are packaged under a protective atmosphere – specifically argon in sealed glass ampoules – due to the metal’s extreme reactivity. Potassium acetate is available in both 99.99+% for precise analytical or synthetic applications and 99+% for larger quantities.
Potassium bromide, on the other hand, is available in purities up to 99.999%, and anhydrous potassium carbonate up to 99.99%. These gradations allow for targeted selection according to the specific purity and availability requirements. For questions regarding the appropriate purity level, ChemPUR’s expert team is available for personal consultation.
What forms does ChemPUR offer?
Consistent quality is a prerequisite for potassium to be reliably used in various forms – and ChemPUR, as an ISO 9001:2015 certified company, ensures precisely that. Metallic potassium is supplied as ingots under argon in glass, while the compound range includes acetates, carbonates, halides, phosphates, sulfates, nitrates, silicates, and many other compound classes.
Should you require a form or specification not included in the standard range, custom-made special orders are also possible. Through our worldwide dealer network, even unusual requirements can be met. As a family business with short internal communication channels, there is no detour via call centers: expert staff provide direct and personal advice. For inquiries about available forms and packaging, the ChemPUR team is at your disposal.
For which applications is potassium used?
Through a worldwide dealer network, ChemPUR supplies customers from research, development, and industry with potassium in the required forms and purities – as the applications for this element are diverse. Potassium compounds play a central role in the synthesis of inorganic and organic compounds, in catalysis, and in electrochemistry.
Potassium hydroxide, for example, is an important reagent in the chemical industry; potassium carbonate is used in glass manufacturing and as a synthesis chemical; potassium nitrate, in turn, is used in pyrotechnics and as an oxidizing agent, among other things. High-purity potassium bromide is an established material for IR optics and spectroscopic applications. The high-purity metal itself is used in specialized electrochemical and material science investigations. For a professional assessment of which potassium product is suitable for a specific application, the ChemPUR team is personally available.
Which potassium compounds are available at ChemPUR?
Potassium is available at ChemPUR as a high-purity metal and in a wide selection of potassium compounds. Metallic potassium is offered as an ingot with 99.95% purity in a sealed glass ampoule under argon. Due to the material’s reactivity, it is classified as dangerous goods and handled accordingly.
For classic laboratory, synthesis, and industrial applications, the range includes potassium acetate, potassium carbonate, potassium hydroxide, potassium nitrate, potassium oxalate, potassium phosphates, and potassium sulfates, among others. Halides such as potassium bromide, potassium chloride, and potassium iodide are also available in various purity levels.
For more specialized material science or inorganic applications, ChemPUR also offers potassium borates, potassium molybdates, potassium niobate, potassium metavanadate, as well as various fluorocomplexes, for example with silicon, titanium, or zirconium. The range is supplemented by special compounds such as potassium bismuthate, potassium antimonyl tartrate, and numerous precious metal and complex salts. Which potassium compound is suitable depends on purity, solubility, reactivity, and the desired application area. If you are looking for a specific specification or compound, our expert team will be happy to assist you with the selection.
Is potassium delivered worldwide?
The logistical conditions to be considered when delivering potassium vary significantly. ChemPUR delivers potassium products internationally, with special transport regulations applying to the high-purity metal due to its extreme reactivity: potassium ingots are classified as dangerous goods, which is why a separate dangerous goods surcharge applies to orders, for which an inquiry in advance is recommended. Potassium compounds are subject to different shipping regulations depending on their classification. For international deliveries, the ChemPUR team provides information on the applicable regulations and shipping conditions. Inquiries about delivery options and shipping conditions are answered directly by ChemPUR’s expert team.
Why is ChemPUR the right contact for potassium?
Our potassium product range covers both high-purity metal and an extensive selection of compounds – from standard chemicals in kilogram quantities to high-purity special grades for research. ChemPUR is ISO 9001:2015 certified, which ensures consistently high quality standards across all product categories.
What makes us special: Through a worldwide dealer network, materials not part of our regular stock can also be procured. Custom-made special orders are possible if standard products do not meet requirements. As a family business, we operate without call center structures: inquiries are processed directly by experienced specialists, enabling short response times and individual support. Anyone requiring potassium in defined purities, quantities, or special forms will find ChemPUR to be a competent partner with many years of experience in high-purity metals and inorganic specialty chemicals.
What distinguishes potassium from other elements?
Potassium is characterized by its high reactivity and its function as a versatile alkali metal. Precisely these properties make it interesting for research, synthesis, and specialized industrial applications. As a strongly electropositive metal, potassium can be used as a reactant, reducing agent, or starting material for potassium compounds in suitable reaction systems.
Another advantage is the wide range of available potassium compounds. Salts such as potassium acetate, potassium carbonate, potassium chloride, potassium bromide, potassium nitrate, or potassium sulfate are used in numerous chemical and analytical applications. Specialized compounds such as potassium niobate, potassium molybdate, potassium metavanadate, or precious metal complex salts open up additional possibilities in materials research, synthesis, and technical processes.
For users, potassium is particularly relevant when a well-defined potassium source, high purity, or a specific compound class is required. ChemPUR offers both metallic potassium and a broad spectrum of potassium compounds in various purity levels for this purpose. Our expert team will be happy to assist you in selecting the appropriate quality or compound.
