Calcium Metal

 

Calcium Metal: Silvery white slightly soft metal with a metallic luster.

Melting point: 842°C, molecular formula: Ca, density: 1.55g/cm³ (relative density water = 1).

Stability: Unstable, Class 4.3 hazardous chemicals.

Main application: It is used to make alloys with aluminum, copper, and lead, is also used as a reducing agent for glass making, and is routinely used as an alloy deoxidizer/desulfurizer.

HS code:2805120090.

It functions to desulfurize, deoxidize, enhance the fluidity of molten steel, and promote the rapid floatation of inclusions in the molten steel.

In the steel industry, the main use of metal calcium is to process metal calcium grains, and then make calcium iron lines or pure calcium lines.

It is used for refining outside the furnace of steel. Its role is desulfurization and dehydration, Promoting the rapid rise of debris in steel water, generally used for the production of high-quality steel.

Use pure calcium metal as a dehydrator to create waterless alcohol.

In the oil industry, it is used as a desulfurization agent.

 

 

Step 1: Burn the marble (CACO3), commonly known as white, and make it into lime (CA0);

Step 2: Mix the lime (CA0) quickly with the aluminum powder (AL), suppress the ball with a ball machine into a flat ball with a length of about 4cm;

Step 3: Put the flat ball into a 1200 -degree high -temperature restore can, and then draw a vacuum;

Step 4: Aluminum powder and lime react under high-temperature conditions, generating alumina and metal calcium steam;

Step 5: Metal calcium steam condenses in the water-cooled section of the restored tank to form metal calcium crystals;

Step 6: Metal calcium crystals can be processed into the metal calcium products required, such as metal calcium grains and metal calcium powder.
