Application

Iron(III) phosphate dihydrate with a purity of ≥99.99% trace metals can be used in various research applications. It is suitable to use as a precursor in the production of lithium iron phosphate (LiFePO4) for use in lithium-ion batteries (LIBs) particularly in the cathode material. It can be used as an efficient catalyst for the chemo selective acetylation of alcohols and phenols under solvent free condition at room temperature and with high yields. Apart from the product also widely used in waste water purification and ferroelectric applications. [,]

Features and Benefits

With 99.99% purity, the product contains minimal trace metal impurities, making it ideal for use in sensitive processes where contamination must be strictly controlled. The high purity ensures consistent performance, which is essential in research and production environments that require reproducibility and precision.

General description

Iron(III) phosphate dihydrate, with a purity of ≥99.99% trace metals, is a high-purity chemical. It is a hydrated form of iron(III) phosphate, appearing typically as a solid with a slightly off-white to light yellow color. It comes with a purity ≥99.99% , and trace metal content ≤ 100 ppm. Its high purity makes it suitable for sensitive applications where trace metal contamination must be minimized.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product belongs to an Enabling category. Iron phophate dihydrate precursor enables greener synthesis of high-performance LiFePO4/C cathodes, demonstrating sustainable production for advanced lithium-ion batteries, offering a promising solution in greener energy storage technology.
