Calcium barium silicon is a kind of ferroalloy deoxidizer with silicon, barium and calcium as the main components, which is widely used in the steelmaking industry. Its effects include deoxidation, desulfurization and dephosphorization, as well as inoculant and metamorphic agent in the casting process (e.g. to improve graphite morphology). Silicon-barium-calcium products usually implement national standards, with low content of harmful elements (sulfur and phosphorus) and various specifications (blocks, grains, powders, balls), which are suitable for the production of special steels such as stainless steel. Anyang, Henan Province, is one of the main producers of barium and calcium silicon, and by 2025, local enterprises will have an annual production capacity of tens of thousands of tons

Product composition and characteristics

The main components of silicon barium calcium are silicon (Si), barium (Ba), calcium (Ca), often containing aluminum (Al), iron (Fe) and other elements。 The content of harmful elements sulfur and phosphorus is low, and the national standard quality standards are implemented。 Features include:

• The deoxidation speed is fast, the slag is formed early, and the energy is saved 

• Strong anti-recession ability to prevent ductile iron whitening 

• It is suitable for stainless steel refining process and does not erode the ladle lining

Fields of application

Barium calcium silica is mainly used for:

• steelmaking: As a deoxidizer and desulfurizer 

• foundry: Acts as an inoculant (increases graphitized core) to improve the structure of cast iron
