Product Description
Product introduction
Chinese name: Calcium

Appearance: silver white to off white powder
EINECS accession number: 231-179-5
Molecular weight: 40.08
CAS Registry Number: 7440-70-2
Characteristic and superiority
Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium; melts at 815 ° C. The chemical nature of Calcium Metal is very lively. In the air, calcium is rapidly oxidized, coated with an oxide film. When heated, calcium burns and emits a brick-red beautiful light. Calcium and cold water are slow acting, and intense chemical reactions take place in hot water, releasing hydrogen (lithium, sodium and potassium can react violently even in cold water). Calcium is also very easy with halogen, sulfur, nitrogen and other compounds.
Application
1, deoxidation, desulfurization, degassing in steelmaking and cast iron;
2, in the production of chromium, niobium, samarium, thorium, titanium, uranium and vanadium and other deoxidation;
3, as an alloy material used in the lead industry to produce maintenance-free automotive batteries, calcium-lead alloy can increase the strength and improve corrosion resistance and creep resistance;
4, in a variety of non-ferrous metals, rare earth metals and refractory metals as a deoxidizing agent;
5, In the production of aluminum, beryllium, copper, lead, magnesium and other nonferrous alloy production as an alloying agent (blend);
6, in the production of high-purity steel and non-ferrous alloy as a deoxidizer;
7, In addition to bismuth in lead smelting industry and lead alloys; and other uses.

Emergency treatment
First, the leak emergency response
Isolate leaking pollution area and restrict access. Cut off the fire. Recommended emergency personnel to wear self-contained breathing apparatus, wear fire protective clothing. Do not touch the spill directly. A small amount of leakage: rinse with plenty of water, diluted with water into the waste water system. Large leaks: water wetting, and then collected for recycling or shipped to the disposal of waste disposal sites.
Second, protective measures
Respiratory protection: Wear a hood-type, electrically-powered, filtered respirator when possible exposure to dust.
1 Eye protection: Respiratory protection has been protected.
2 body protection: wear plastic protective clothing.
3 hand protection: wear rubber gloves.
4 other: the work site is strictly prohibited smoking.
Third, first aid measures
1 Skin contact: Immediately remove contaminated clothing, rinse with plenty of water for at least 15 minutes. Get medical attention.
2 Eye contact: Lift the eyelid immediately, rinse thoroughly with plenty of running water or saline for at least 15 minutes. Get medical attention.
3 Inhalation: Remove quickly from the scene to fresh air. Keep the airway clear. If breathing is difficult, give oxygen. If breathing stopped, resuscitate immediately. Get medical attention.
5 Ingestion: Gargle with water, to drink milk or egg white. Get medical attention.
6 fire fighting methods: No water, halogenated hydrocarbon agent rescue, it is not appropriate to use carbon dioxide fire extinguishing. In the fire, such as improper use of fire extinguishing agents, but also violent reactions can occur, causing an explosion, we must pay special attention to fire safety and rescue. Extinguishing agents: dry graphite, soda ash, sodium chloride powder.
