Direct Sales Ca, Si, C, Al, P, S 0-2mm 10-50mm Calcium Silicon Alloy
Silicon calcium (Si-Ca) is an alloy composed primarily of silicon (Si) and calcium (Ca), often used in metallurgical processes, particularly in the steelmaking and cast iron industries. It is typically produced in a furnace by reducing silica (SiO₂) and lime (CaO) with a reducing agent such as carbon. The alloy usually contains varying proportions of silicon and calcium, with common compositions ranging from 30-60% silicon and 10-30% calcium, along with small amounts of other elements like aluminum, iron, and carbon.
Key Properties and Uses:
-
Deoxidizer:
Silicon calcium is widely used as a deoxidizing agent in steelmaking. It helps remove oxygen from molten steel, improving its quality and reducing the formation of oxides that can weaken the final product.
-
Desulfurizer:
The alloy is also effective in removing sulfur from molten metal, which enhances the mechanical properties and cleanliness of steel and cast iron.
-
Inoculant:
In cast iron production, silicon calcium is used as an inoculant to modify the microstructure of the iron, promoting the formation of graphite and improving strength, ductility, and machinability.
-
Improves Fluidity:
The addition of silicon calcium to molten metal can improve its fluidity, making it easier to cast and shape.
-
Reduces Inclusions:
By reducing impurities and non-metallic inclusions, silicon calcium helps produce cleaner and higher-quality metal.

Physical and Chemical Characteristics:
-
Appearance: Silicon calcium is typically a grayish, metallic solid, often supplied in granular, lump, or powder form.
-
Melting Point: The alloy has a relatively low melting point compared to pure silicon or calcium, making it easy to dissolve in molten metal.
-
Reactivity: It is highly reactive, especially at high temperatures, which makes it effective in metallurgical processes.
