2014 China Strontium Hard Sintered Barium Ferrite Magnets
Ferrite magnets, made by molding powder mixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also called ceramic magnet. Along with deepening of research, some additives such as cobalt (Co) and lanthanum (La) are mixed together to improve the magnetic performance. The molded powder metallic green is sintered inside a temperature controlled furnace what is heated with electricity or coal. Though hard ferrite magnet is with low magnetic property, it is still a preferable choice to engineer in their design due to several factors: abundantly available raw material,the cheapest cost among permanent magnet family, low density, excellent stability of chemistry, high maximum working temperature and Curie temperature.

Features
1. Ferrite or ceramic magnets are still the most widely used magnets with a maximum energy product of 1 to ± 4.3 MGOe.
2. Due to the environmental requirements which are becoming more stringent barium ferrite has been replaced by strontium ferrite during the last years.
3. Ferrite is the cheapest magnetic material and has a high corrosion resistance making coating unnecessary.
4. This magnetic material is hard and fragile and must be processed with diamond, preferably when it is not in a magnetic state.
Applications
Speaker magnets
DC brushless motors
Magnetic Resonance Imaging (MRI)
DC permanent magnet motors (used in cars)

Salt Spray Test :
Mainly test the surface treatment against the corrosion. Usually the tested samples will be continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface.
Projection Instrument:
Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.
PCT Instrument:
Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .
Heat& Humidity Instrument:
Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity
Hysteresgraph:
Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
