Ferrosilicon 72 is a type of ferrosilicon, the classification of ferrosilicon is divided into 21 grades according to the content of silicon and its impurities.The main raw material for smelting ferrosilicon is silica ore (quartz, silica), SiO2 in the ore is generally higher than 96%, FeSi72 is a common grade of ferrosilicon.

Nodularizer is widely used in foundry field, can promote in the ball mill cast iron into the spherical graphite crystals additives, get the favour of the foundry customers, but the quality of the products on the market is uneven, as a type of nodularizer, offer but differ a lot, greatly increases the difficulty to select high-quality nodularizer, star metallurgy factory technical engineers today as we summarize several tips to judge the quality of nodularizer, come and look at it together;

Electrolytic manganese metal is a single metal which is obtained by leaching manganese ore with acid and then sent to electrolytic cell for precipitation.Appearance like iron, irregular flake, strong and brittle, one side bright, the other rough, silver-white to brown, after processing to powder silver gray;It is easily oxidized in air, dissolves and displaces hydrogen in the presence of dilute acids, and dissolves water to give off hydrogen at slightly higher room temperature.

Metal silicon powder refers to the powder made of metallic silicon after processing, which is often used as raw material in refractory materials and powder metallurgy industries.Metallic luster, high melting point, good heat resistance, high resistivity.Its main uses are:

High carbon silicon is also called silicon carbon alloy. It is a by-product of metal silicon. Its main elements are silicon and carbon, and the remaining elements are sulfur, phosphorus and carbon dioxide

Silicon calcium powder, as the name suggests, is the product of silicon calcium alloy after grinding and screening
