Introductin of Pure Calcium Metal
When it comes to calcium, we think that it is not strange for everybody. Retrospecting our chemistry knowledge, we can recall that it is No. 20 element in periodic table and located in the second main group of the fourth period. So, according to these, we can infer that it is more active than most of elements except for potassium. When it is exposed to air, oxide and nitride are generated in the surface. Ca metal is an alkali, silver-white metal with luster and used in process of alloy steel production as deoxidizer and desulphurizer generally.
Production Method of Pure Calcium Metal
There are two methods for producing calcium metal at present, those are electrolysis and reduction method respectively.
Including, reduction method is easy relatively. We take it as an example to introduce its producing method roughly. First of all, we make limestone calcined until it changed into calcium oxide, then, crush it and mix with Al powder in a certain proportion. Calcium vapour and CaAl are formed due to their reaction. Moreover, it reduced into crystalline Ca. Last but not least, it forms calcium ingot.
Purpose of Pure Calcium Metal
It has plenty of applications for calcium metal such as deoxidizer, desulphurizer, reducing agent, making batteries,etc. Including, we only talk about these two applications that related industry field —— deoxidizer and desulphurizer.

Export Operation Process of Pure Calcium Metal
Export operation can be divided into 4 steps approximately:
Booking order;
MSDS;
Packing;
Customs clearance.
For booking order, it is paramount to note G.W.(gross weight), N.W.(net weight) and any other parameters. You should focus on harmful factors for calcium metal such as friction, collision, transportation environment and so on.
