Why The Higher The Whiteness Of Alumina, The Better The Quality

Alumina powder is widely used in new ceramic materials and industrial production. Good quality products can help improve production efficiency. Therefore, we must carefully control the quality when selecting products to prevent quality problems during use. not effectively.

1. The purity content of alumina powder should be high, and the oxides of elements such as silicon and iron should be as low as possible. To ensure its purity and whiteness, the higher the purity, the higher the whiteness.

2. The content of heavy metal elements harmful to the human body must be strictly required. Radiation is a very large measure.

3. The whiteness of alumina should be as high as possible. Whether alumina or molecular sieve, the whiteness mainly depends on the raw material. For new ceramic materials, the whiteness does not affect the mechanical properties and processing performance of the material, but the whiteness is high and gives people a good feeling, the same performance whiteness High ones have more competitive advantages.

4. The lower the oil absorption, the better. The specific surface area directly determines the oil absorption, and the firing temperature absolutely determines the specific surface area. The higher the firing temperature, the smaller the specific surface area and the lower the oil absorption. Special industries need to use products with lower oil absorption. At this time, surface activation treatment is required and processed into activated alumina to meet customer requirements.

5. The fineness should be appropriate, not the finer the better, and the particle size distribution should also be determined according to needs.

6. Activation or non-activation should be determined according to the needs of downstream users.
