Yttrium ferrite powder (Y₃Fe₅O₁₂) is a magnetic functional ceramic material with a garnet crystal structure. It has excellent magneto-optical properties, low magnetoresistance loss, narrow magnetic resonance linewidth and good chemical stability. It is widely used in microwave communications, magneto-optical devices, non-contact sensors and other fields. YIG has good magnetic response at GHz frequency and is an important research and application object in the field of magnetic materials.
VIMATERIAL provides YIG powder with high purity, high specific surface area and excellent sinterability. The Y:Fe ratio is strictly controlled during production to ensure the crystal phase purity and magnetic properties to support customization of different particle sizes and morphologies.Contact Us.

Magneto-optical devices and magneto-optical modulators: Yttrium ferrite powder can be used for Faraday rotators, magneto-optical modulators, optical isolators, etc. due to its excellent magneto-optical effect. It is a key material for optical communication and laser systems.
Magnetic sensors and non-contact detection devices: Yttrium ferrite powder is sensitive to magnetic fields and has a stable response, suitable for magnetic probes, current sensors and non-contact displacement measurement devices.
Magnetic storage and spin electronics: As part of magnetic films or composite materials, Yttrium ferrite powder supports spin wave transmission and regulation, and is an important research platform in the field of spin electronics.
Our products use high-purity raw materials, strictly control the molar ratio of raw materials, avoid second phase precipitation,
use advanced production processes, multi-stage temperature control, scientific inspection methods, XRD, SEM/TEM, ICP-MS, VSM, BET, to produce higher quality products.
Small size packaging: 50g/100g/500g/1kg and other capacities, external PE bottle packaging, vacuum bag protection, packaging specifications can be customized.
Bulk packaging: 5kg/10kg/25kg aluminum foil bag, external standard barrel double protection, and finally fixed on the pallet.
Yttrium ferrite powder should be stored in a sealed container in a cool and dry environment to avoid long-term exposure to air to absorb moisture or oxidation. It should be stored at low temperature and away from light and fully dispersed before use.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
