Indium sulfate hydrate (2:3:9) - Introduction
Indium sulfate nonahydrate has the chemical formula In2(SO4) 3.9H2O and is a colorless crystalline solid. The following are the main properties and uses of indium sulfate nonahydrate:
Nature:
1. indium sulfate nine hydrate is soluble in water, the solution is acidic.
2. it is hygroscopic, so it is necessary to prevent contact with humid air.
3. will lose crystal water when heated to about 200 degrees Celsius.
Use:
1. Indium sulfate nine hydrate is commonly used as a chemical reagent, mainly used in the field of analytical chemistry, such as the determination of molybdenum, the preparation of other indium compounds.
2. It is also widely used in the preparation process of semiconductor materials, for the preparation of indium compounds, indium phase seeding agents, etc.
Preparation Method:
A preparation method of indium sulfate nonahydrate is to add sulfuric acid to a solution of indium powder or indium oxide to react, followed by crystallization. During the preparation, attention should be paid to the control of reaction conditions and the selection of appropriate solvents.
Safety Information:
1. indium sulfate nine hydrate is a chemical substance, the use should strictly abide by the relevant safety procedures, to avoid direct contact with the skin and eyes.
2. in operation, need to wear protective glasses, gloves and other personal protective equipment.
3. Avoid inhaling its dust and ensure that it is operated in a well-ventilated place.
4. In case of unintentional contact with skin or eyes, rinse with plenty of water immediately and seek medical assistance in time.
5. storage should be sealed, away from the fire and flammable substances.
