8 How are Ceramic Magnets Made

 Ceramic magnets, often referred to as ferrite magnets, including ceramic block magnets and ceramic disc magnets, are produced through a meticulous and detailed process. The initial step involves blending strontium carbonate and iron oxide. This mixture is then subjected to a chemical conversion at extremely high temperatures ranging between 982-1093°C (1800-2000°F). The outcome of this process yields hard ferrite. This resultant material is further processed by wet milling to reduce it into fine particles. Following this step, the powders undergo a sintering process, which can either be dry or wet compacting using a hydraulic press. Significantly, this sintering is carried out in the presence of a magnetic field and at elevated temperatures nearing 1093°C (2000°F). The culmination of these precise steps results in the creation of the widely used ceramic magnets we see in various applications today.
