Smelting methods of silicon barium
There are two main methods of smelting barium silicon:
One-step smelting method: barite (a mineral containing barium), silica, coke, steel chips, silicon carbide and other materials are added to the submerged thermal electric furnace for smelting.
Two-step smelting method: firstly, ferrosilicon is smelted by submerged thermal electric furnace, and then ferrosilicon is added to the intermediate frequency furnace with barium-containing raw materials for smelting and refining to obtain silicon-barium alloy.
physical properties of silicon barium
Density: The density of silicon-barium alloys is usually between the density of silicon and barium, depending on the ratio of silicon and barium.
Melting Point: The melting point of silicon-barium alloys is usually lower than that of pure barium because the addition of silicon lowers the melting point of the alloy.
Thermal and electrical conductivity: The thermal and electrical conductivity of silicon-barium alloys is generally lower than that of pure metals, but the exact value depends on the composition of the alloy and the preparation process.
Mechanical properties: The strength and hardness of silicon-barium alloys are usually higher than that of pure silicon and pure barium, and they have good ductility and toughness, depending on the composition and preparation process of the alloy.
