Alumina granulated powder is an important industrial material with excellent properties such as high purity, high hardness and high melting point.
Alumina granulated powder is an important industrial material, widely used in ceramics, electronics, machinery and other fields. The following is a detailed introduction to the concept, properties, preparation methods and applications of alumina granulation powder.
I. Concept
Alumina granulation powder, simply put, is the alumina powder through a specific process of granulation treatment, forming a certain shape and size of the granular material. This material has excellent physical and chemical properties, such as high hardness, high melting point, good insulating properties.
II. Properties
The main component of alumina granulation powder is alumina, which has the characteristics of high purity, high hardness and high melting point. In addition, the granulated alumina powder has better fluidity, compaction and sintering, which is convenient for processing and molding.
Preparation method
The preparation of alumina granulation powder mainly includes the following steps:
1. raw material preparation: select high purity alumina powder as raw material.
2. add additives: according to need, add appropriate amount of binder, solvent and other additives.
3. Mixing: Mix the raw materials and auxiliaries and stir well.
4. granulation: through spray drying, drum granulation and other methods, the mixed powder is made into granules.
5. Screening and drying: sieve the powder after granulation, remove unqualified particles, and dry the qualified particles.
Application
Alumina granulation powder is widely used in the following fields:
1. ceramic field: used in the manufacture of high-performance ceramic materials, such as ceramic knives, ceramic bearings and so on.
2. Electronic field: used to manufacture electronic ceramics, substrates, resistors, etc.
3. Mechanical field: used as abrasives, fillers and coating materials for manufacturing various mechanical parts.
4. Other fields: also used in metallurgy, chemical industry, aerospace and other fields.
V. Summary
Alumina granulated powder is an important industrial material with excellent properties such as high purity, high hardness and high melting point. Its preparation method includes raw material preparation, adding additives, mixing, granulation, sieving and drying and other steps. Alumina granulation powder is widely used in ceramics, electronics, machinery and other fields, which is important for improving product quality and reducing production costs. With the continuous development of science and technology, the application prospect of alumina granulation powder will be more broad.
