Silicon Barium With Special Characteristics

Silicon-barium alloy is an alloy material made by mixing silicon and barium in a certain proportion and then smelting at high temperature.  It is not easy to react chemically with other elements. The barium in silicon-barium alloy is an alkaline earth metal with a strong affinity for oxygen, so silicon-barium alloy is often used as a deoxidizer in steel smelting. Silicon-barium alloy can resist the erosion of acid and alkali media and is widely used in the chemical industry. The density of silicon-barium alloy is usually between the density of silicon and barium, depending on the ratio of silicon to barium. The melting point of silicon-barium alloy is usually lower than that of pure barium, and the addition of silicon reduces the melting point of the alloy.

The thermal conductivity and electrical conductivity of silicon-barium alloy are usually lower than those of pure metals, but the specific values ​​depend on the composition and preparation process of the alloy. The strength and hardness of silicon-barium alloy are usually higher than those of pure silicon and pure barium, which is due to the lattice distortion and solid solution strengthening effect during the alloying process. The ductility and toughness of silicon-barium alloy depend on the composition and preparation process of the alloy, and may show good ductility and toughness in some cases.It has excellent chemical and physical properties and is widely used in metallurgy, electronics, chemical industry and other industrial fields.

Silicon barium is a composite ferroalloy product. Its production method can be operated according to the production technology of ferrosilicon 75. In order to increase the barium content of silicon barium, about 2% - 4% calcium oxide is usually added during smelting. If silicon barium is to be used for slag removal, a certain proportion of iron ore and steel scraps must be added during production.

Silicon-barium alloy is mainly used as a deoxidizer and alloy additive in steel smelting to reduce the oxygen content in steel, improve the quality and performance of steel, and improve the physical and chemical properties of steel such as mechanical properties, hardness, wear resistance, and corrosion resistance. As an inoculant, silicon-barium alloy is suitable for gray cast iron and ductile iron. It can promote the formation of graphite nodules of "A" type graphite. At the same time, it can form nuclei in a wide temperature range, has strong spheroidization ability and anti-degradation ability, and can effectively prevent the tendency of castings to white cast iron. Silicon-barium alloy can also be used in the chemical and electronic fields to manufacture semiconductor materials, as well as in the medical field for radiotherapy and diagnosis.
