Description

Ferrite CAS NO 1317-54-0 is a class of ceramic compounds composed primarily of iron oxide combined with one or more other metallic elements, exhibiting ferrimagnetism. This material is fundamental for creating permanent magnets, magnetic cores, and components that require high magnetic permeability with low electrical conductivity. It is essential for manufacturers in the electronics, telecommunications, automotive, and power supply industries seeking reliable, cost-effective magnetic solutions.

Application

• Permanent Magnets: Used in loudspeakers, electric motors, generators, and magnetic separators.
• Soft Magnetic Cores: Essential for high-frequency transformers, inductors, and choke coils in switch-mode power supplies and telecommunications equipment.
• Electromagnetic Interference (EMI) Suppression: Incorporated into ferrite beads and cores to filter out high-frequency noise in electronic circuits.
• Microwave Devices: Utilized in isolators, circulators, and phase shifters for radar and satellite communication systems.
• Magnetic Recording Media: A key component in the magnetic layer of older hard disk drives and audio/video tapes.
• Biomedical Applications: Employed in magnetic resonance imaging (MRI) contrast agents and magnetic hyperthermia for targeted cancer therapy.
• Automotive Sensors: Used in crankshaft position sensors, wheel speed sensors, and other critical vehicle electronics.

Quality Control

Our ferrite powders and components are manufactured under strict process controls to ensure batch-to-batch consistency in magnetic and physical properties. Quality is verified against key parameters including saturation magnetization, coercivity, Curie temperature, particle size distribution, and chemical purity. Certificates of Analysis (COA) detailing these specifications are available for every shipment. We adhere to relevant ISO quality management standards to meet the rigorous demands of the electronics and automotive sectors.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong magnetic fields during storage to prevent undesired magnetization or demagnetization of pre-formed components. The powder form is hygroscopic (moisture-sensitive) and should be protected from atmospheric moisture to prevent agglomeration and property degradation.
