一般描述

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.

应用

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. [,]

特点和优势

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.
