In a major breakthrough for the sensor industry, researchers have unveiled groundbreaking applications of silicon barium in the development of high-performance, cutting-edge sensor technologies.

In 2026, the foundry industry is undergoing a structural transformation driven by two key forces: higher casting quality standards and stricter environmental compliance requirements. Under these conditions, High Carbon Silicon has gradually become a preferred auxiliary material in cast iron production. Compared with traditional deoxidizers and carburizers, its low impurity content, stable composition, and integrated functionality provide foundries with a more controllable and sustainable solution. For manufacturers with long-term experience in ferroalloy and silicon-based materials, the shift toward High Carbon Silicon reflects not only regulatory pressure, but also a clear trend toward process stability and quality consistency.

In January 2026, magnesium ingots (taking the mainstream 99.90% grade as an example) generally trended as rising first, then correcting, and stabilizing with a rebound in the late month. The mainstream spot transaction price fluctuated in the range of 16,000-16,800 CNY/ton. The core drivers were cost support combined with strong intentions to maintain prices; transaction volume was dominated by downstream rigid demand and pre-festival stockpiling, regional price spreads remained stable, and the price edged up slightly at the end of the month due to tight supply. Below is the full-month price information (Tax-inclusive, unit: CNY/ton, un-pickled with simple packaging).

Silicon slag is a by-product from the production of industrial silicon and silicon alloys. It is gaining attention for its multifunctional use in the steel and foundry industries. Its main components include silica (SiO₂, 40%-70%), alumina (Al₂O₃, 5%-20%), iron oxide (Fe₂O₃, 3%-15%), and calcium-magnesium oxides (CaO+MgO, 2%-10%). With high cost-effectiveness and environmental benefits, silica slag is becoming an important material in modern industry.

High carbon silicon (Si-C alloy) is a crucial alloy additive in metallurgy, offering unique benefits that enhance steelmaking and casting processes. With high carbon and silicon content, this alloy improves efficiency, reduces costs, and enhances material properties. Below, we explore the top five applications of high carbon silicon in metallurgy and why it’s a preferred choice for manufacturers worldwide.

how do you choose the best silicon carbon alloy for foundry use? This guide explores key factors, benefits, and top recommendations to help foundries make informed decisions.

High Carbon Silicon (Si–C alloy) is an emerging alloy material widely used in the steelmaking and foundry industries. Among various grades, High Carbon Silicon 68 Si 18 C has gained attention for its excellent cost-performance ratio and stable alloying effects. This alloy typically contains 68% silicon, 18% carbon, and small amounts of iron, aluminum, and calcium. It combines the deoxidizing properties of silicon with the carbon-enhancing ability of graphite, making it an ideal substitute for ferrosilicon in steel production. In modern steel plants aiming to reduce costs without sacrificing quality, high carbon silicon has become a preferred choice in place of traditional FeSi 75 or FeSi 72.
