    Soft magnetic ferrite sheetSoft Ferrite is a special magnetic material composed of elements such as iron, oxygen, titanium, nickel, zinc, etc. It has the characteristics of high conductivity, high magnetic permeability, high magnetic saturation strength, and low magnetic loss. Soft magnetic ferrite sheets are widely used in electronic components, communication equipment, power tools, automotive electronics, medical equipment and other fields, and are one of the indispensable materials in modern technology.
1、 Classification of Soft Magnetic Ferrite Plates
Soft magnetic ferrite sheets can be divided into three categories based on their chemical composition and magnetic properties: magnesium zinc ferrite, nickel zinc ferrite, and manganese zinc ferrite.

1. Magnesium zinc ferrite is a material composed of elements such as magnesium, zinc, iron, and oxygen. It has high electrical conductivity, magnetic permeability, and magnetic saturation strength, as well as low magnetic loss and thermal expansion coefficient. Magnesium zinc ferrite sheets are widely used in high-frequency electronic components, communication equipment, power tools, and other fields.

   
   

2. Nickel zinc ferrite is a material composed of elements such as nickel, zinc, iron, and oxygen. It has higher electrical conductivity, magnetic permeability, and magnetic saturation strength than magnesium zinc ferrite, but the magnetic loss is relatively high. Nickel zinc ferrite sheets are widely used in high-frequency electronic components, communication equipment, power tools, automotive electronics, medical equipment, and other fields.

   
   

3. Manganese zinc ferrite is a material composed of elements such as manganese, zinc, iron, and oxygen. It has higher conductivity, lower magnetic loss and thermal expansion coefficient, but relatively lower magnetic permeability and magnetic saturation strength. Manganese zinc ferrite sheets are widely used in low-frequency electronic components, inductors, transformers, and other fields.

2、 Preparation method of soft magnetic ferrite sheet
The preparation methods of soft ferrite sheets mainly include high-temperature sintering, sol gel method, chemical coprecipitation method, etc. Among them, high-temperature sintering method is the most commonly used preparation method. The high-temperature sintering method is toferrite powderAfter mixing with additives, sintering is carried out at high temperature to make it a high-density block material, which is then cut, polished and other processes to produce the desired shape and size. Sol gel method is to mix metal ions and organic matter to form colloid, and then obtain ferrite materials after drying and sintering. The chemical co precipitation method is to mix metal salts and oxidants to form precipitates, which are then dried and sintered to obtain ferrite materials.
