Silicon Barium Powder

Silicon Barium Powder is an artificial composite ferro alloys product. It is typically made by blending silicon powder and barium powder in specific ratios, followed by refining in a high - temperature furnace. This precise manufacturing process ensures a consistent and high - quality end product. The main chemical components of Barium Silicon Powder usually include silicon (Si), barium (Ba), along with small amounts of calcium (Ca), aluminum (Al), and other trace elements. For example, common specifications might have silicon content ranging from 60% - 72%, barium content from 2% - 12%, calcium around 1% - 2.5%, and aluminum at 1% - 3%.​

SiBa Powder comes in various specifications to meet different industrial requirements. Here are some common model compositions and their corresponding content percentages:​

Common sizes of SiBa Powder include 0.2 - 0.8 mm, 1 - 3 mm, 3 - 8 mm, and 8 - 15 mm. However, it can also be customized according to specific customer needs. For example, a finer size of 0.2 - 1 mm might be used for more precise inoculation in certain casting processes, while larger sizes like 8 - 15 mm could be suitable for inoculation in the furnace.​

Steelmaking field

Deoxidizer:

The silicon and barium elements in silicon-barium powder have strong deoxidation ability and can quickly react with oxygen in molten steel to produce silicon dioxide and other substances, greatly shortening the deoxidation time. Its deoxidation effect is higher than that of silicon-calcium alloy, and there is no smoke or sparks during the deoxidation process, which can improve the quality of steel.

Desulfurizer:

Barium is one of the main elements for desulfurization during steelmaking. Silicon-barium powder can effectively treat sulfur and other harmful elements, reduce the sulfur content in steel, and improve the purity of steel.

Improve the morphology of inclusions:

It can improve the morphology of impurities in molten steel, so that impurities do not block the water outlet, extend the life of the smelting furnace, and change the properties and distribution of non-metallic inclusions in steel, and improve the toughness, ductility and other properties of steel.

Casting field

Inoculant:

It can promote the formation of type A graphite, refine the eutectic, improve the distribution of graphite, obtain type A graphite in gray iron castings, and improve strength; for ductile iron castings, it can make graphite fine and round, and improve the spheroidization grade.

Reduce the tendency of white cast iron:

effectively reduce the supercooling of molten iron, promote the precipitation of graphite, significantly reduce the tendency of white cast iron castings, reduce the relative hardness, and improve the cutting performance of castings.

Strong anti-recession ability:

The anti-recession time is about 2 times that of ordinary ferrosilicon inoculants, and the addition amount is less than half of that of 75 ferrosilicon inoculants, and it can also prevent the associated spheroidization recession.

Improve cross-sectional uniformity:

The wall thickness sensitivity is small, which can improve the cross-sectional uniformity of castings, reduce the tendency of shrinkage, and improve the quality of castings.

Other fields

It is used as glaze and flux in ceramic production to improve the whiteness, glossiness and mechanical strength of ceramics; it is used as clarifier and flux in glass production to improve the transparency and mechanical strength of glass.

To ensure the quality of Silicon Barium Powder during transportation and storage, it is carefully packaged. Generally, it is first packaged separately in 25 kg small bags, which provides convenience for handling and dosing. These small bags are then packed in a ton bag outside for better protection and ease of transportation in bulk. The packaging is designed to prevent moisture absorption, contamination, and physical damage to the powder. During transportation, proper handling procedures are followed to maintain the integrity of the product. Whether it is transported by road, rail, or sea, the packaged Silicon Barium Powder is protected from rough handling and environmental factors that could potentially affect its quality.​

In conclusion, Silicon Barium Powder is a highly valuable material in the metallurgical and metalworking industries. Its unique combination of properties, diverse applications, and customizable specifications make it an ideal choice for manufacturers looking to enhance the quality of their products.
