Hunan Coran Industry & Commerce Co.,Ltd.

We are a Chinese manufacturer of battery materials----- Activated Chemical Manganese Dioxide (ACMD), Super-purity Nanometer Indium Hydroxide [In(OH)3] and Indium Oxide(In2O3) Powders.
Our ACMD are made from high grade natu
ral MnO2, processed by chemically reducing, diverging, oxidizing, etc. essentially, which are composed of activated MnO2 and chemical MnO2, so they have the advantages as follows: γ-type structure characteristic, large specific surface, good absorption and strong electrochemistry activity.  ACMD are widely used in heavy-duty Zn-Mn dry batteries, owing to their excellent continuous and intermittent discharge properties. Using with EMD or replacing some proportional EMD (usually about 30%~60%), the cost of battery original materials is to be reduced and it remains the same behavior of the batteries, while the price is only about 70% of EMD?. At present our annual production is 5000tons.
Because In(OH)3 and In2O3 are very popularized a
s the first-choice corrosion inhibitor to substitute for mercury, our company cooperated with Powder Metallurgy Institute of Central South University and developed super-purity nanometer Indium Hydroxide and Indium Oxide Powders. They have the following advantages:  large specific area, good dispersion, excellent corrosion inhibition. So they are perfectly suitable for the requirements of the zero mercury. The three-year of application has won good reputation from near twenty
