What's Anisotropic Ferrite Magnet?

Anisotropic ferrite magnet is a type of Permanent Magnet made of iron oxide and barium or strontium carbonate. It is called anisotropic because its magnetic properties are directionally dependent. The magnet is made by pressing the powder into a shape and then heating it to a high temperature. Anisotropic Ferrite Magnets have a high resistance to demagnetization and are commonly used in motors, speakers, and other electronic devices. They are also known for their low cost and good temperature stability.

The production of block ferrite magnets involves the following steps:
1. Raw materials: The first step is to gather the raw materials required for the production of ferrite magnets. The main materials used are iron oxide and strontium carbonate.
2. Mixing: The raw materials are mixed together in a ball mill to form a fine powder. The powder is then sieved to remove any large particles.
3. Pressing: The powder is then pressed into a block shape using a hydraulic press. The pressure applied during pressing is typically around 1000-2000 psi.
4. Sintering: The pressed blocks are then sintered in a furnace at a temperature of around 1300-1400°C for several hours. This process causes the powder particles to fuse together and form a solid block.
5. Machining: Once the blocks have cooled, they are machined to the required dimensions using diamond tools. This process can be quite time-consuming and requires a high degree of precision.
6. Magnetization: The final step is to magnetize the blocks using a strong magnetic field. This gives them their magnetic properties and makes them suitable for use in various applications.

INTRODUCE EQUIPMENT:

Electric kilns are essential equipment for pottery and ceramics artists who need to fire their work at high temperatures. These kilns are powered by electricity and can reach temperatures of up to 2300°F. They come in different sizes and shapes, from small tabletop models to large industrial kilns.
Electric kilns consist of several components, including the heating elements, the temperature controller, the thermocouple, and the kiln shell. The heating elements are responsible for generating heat and are made of high-temperature resistance wires. The temperature controller regulates the temperature inside the kiln and ensures that it stays within the desired range. The thermocouple is a sensor that measures the temperature and sends signals to the temperature controller. The kiln shell is made of heat-resistant materials and provides insulation to maintain the temperature inside the kiln.
Electric kilns are versatile and can be used for various types of firing, including bisque firing, glaze firing, and low-temperature firing. They are also easy to use and require minimal maintenance. However, they can be expensive to purchase and operate, and they require a dedicated electrical circuit to function properly.
Overall, electric kilns are an essential tool for pottery and ceramics artists who want to create high-quality pieces. With the right equipment and techniques, artists can achieve beautiful and unique results that are sure to impress.
