What are the key raw materials for permanent magnet ferrites?

Recently, the surge in prices and shortage of ferrite magnets have drawn attention, with many inquiring about the market trends of ferrite raw materials and what types are available. This article will introduce the key raw materials for permanent magnet ferrite.

The key raw materials for ferrite include iron scales, iron red, iron concentrate powder, strontium carbonate, barium carbonate, rare earth added oxides, pre burned materials, etc. Therefore, the price of ferrite magnets will be affected by these factors.

Below, we will introduce these key raw materials and their sources separately

Iron scale: derived from by-products of steel enterprises.

Iron Red (Fe2O3): Mainly from domestic steel enterprises, some iron red with advantages in price and quality from abroad have also entered the Chinese market.

Iron concentrate powder (mainly composed of ferric oxide, etc.): sourced from Sichuan and other regions in China.

Strontium carbonate: mainly produced in provinces and cities such as Chongqing, Guizhou, Sichuan, Qinghai, Yunnan, Shandong, and Hebei.

Barium carbonate: mainly produced in provinces and cities such as Guizhou, Sichuan, Qinghai, Yunnan, Shandong, Henan, and Hebei.

Rare earth added oxides (lanthanum oxide, cobalt oxide, etc.): sourced from domestic rare earth smelting enterprises.

Pre-sintered materials (strontium and barium materials): Major manufacturers include Beikang Magnetic Materials, Danske, Xinyang, Baosteel, Wuhan Iron and Steel, Pan Steel, Magoco, Benxi Steel, and Ansteel. Most large domestic permanent magnet ferrite manufacturers are capable of producing their own materials.
