Barium Dry Pressing Ferrite Magnetic Powders

Barium Dry Pressing Ferrite Magnetic Powders use for multipoles magnetizing ring magnet,cyliner magnet,sensor magnet,magnetic segment,magnetic tile. The company's sintered permanent magnetic ferrite powder is the semifinished products to make ceramic magnet. It is classified into three specifications and over 20 types.

Procedure Summaries of Making Magnet by Ferrite Materials

There are 6 types of dry pressing ferrite powder for customers: PXC-C1, PXC-C2T, PXC-C3T, PXC-C1, PXC-C2, PXC-C3. The procedure summaries for making magnet are as follows:

The necessary secondary additives have been added into the ferrite powder during the grinding process. Customers shall only add proper quantity of binders and lubricants. The powder must pass through 120 mesh sieve before pressing, so as binders to be uniformly distributed for better orientation.
Please take care of the cleaning of the equipments. Any other materials and impurity should not be mixed into the powder.
During pressing, the pressure required is >=5000N/cm2, and the magnetic field density is >7000 Oe (560KA/m).
The sintering temperature for reference is 1220 Deg.C to 1270 Deg.C. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill.
