Product Name: High-purity tin
CAS No.:7440-31-5
Molecular Formula: Sn
Melting point: 231.89 ℃
Boiling point: 2507 ℃
Properties:
It can form a protective layer of tin dioxide in the air. high purity tin powder, high quality Sn 99.95%,-300mesh, factry price, good service. Grey silvery powder with spherical form or drop form. Tin resists distilled sea and soft tap water, but is attacked by strong acids, alkalis, and acid salts. Oxygen in solution accelerates the attack. When heated in air, tin forms Sn2, which is feebly acid, forming stannate salts with basic oxides. The most important salt is the chloride, which is used as a reducing agent and as a mordant in calico printing.
Application:
High-purity tin is mainly used for compound semiconductor doping elements, high purity alloy, such as superconducting solder.
Security: it has a stimulating effect on the eyes, skin and mucous membranes.
APPLICATION:
Widely used in manufacturing porous bronze bearings self-lubricated, structural parts of powder metallurgy, friction discs, sheathing boards of brakes, clutches, metal-graphite electric brushes, diamond grinding wheels, bronze filters, and also used as the additives of rubbers and plastics, and in the production of chemicals.
