Before choosing a product, it is first necessary to clarify what material needs to be processed. Different materials have significant differences in hardness, surface condition, and processing requirements, and therefore have different requirements for the cutting ability, particle size, and particle morphology of alumina polishing powder. For example, for some metal materials, customers may pay […]
To Determine the Quality of Activated Alumina Powder, the First Step Is to Clarify Its Intended Application Whether an activated alumina powder is of good quality cannot be evaluated independently of its specific application. For activated alumina powder used for adsorption, customers usually pay more attention to specific surface area, pore volume, pore size distribution, […]
Many enterprises will encounter a practical problem after purchasing activated alumina powder: can activated alumina powder that has absorbed moisture continue to be used? How should opened products be preserved in daily life? Activated alumina powder has strong adsorption capacity, so it is prone to contact with moisture in the air during storage and transportation. […]
What is the relationship between activated alumina powder and activated alumina granules? After purchasing activated alumina powder, can it be directly processed into activated alumina granules? The answer is: activated alumina powder can be used as an important raw material for producing activated alumina granules, but it is not possible to obtain qualified products simply […]
Many customers purchasing activated alumina powder for the first time will directly tell the manufacturer: “I need activated alumina powder. Please send me your price.” Although this inquiry is simple, the manufacturer usually cannot provide an accurate quotation immediately. This is because activated alumina powder does not have only one specification, and the requirements for […]
Activated alumina powder is not simply ordinary alumina powder. Activated alumina prepared through specific processes has a well-developed pore structure and a relatively large specific surface area. These characteristics enable it to provide more loading sites for catalyst active components. After forming, calcination, and other processes, activated alumina powder can be made into alumina supports […]
Pseudoboehmite is a hydrated alumina material. It has good peptization properties, a relatively high specific surface area, and an adjustable pore structure, so it is widely used in alumina materials, catalyst supports, and adsorbent materials. Compared with ordinary alumina, an important characteristic of pseudoboehmite is that its structure contains a certain amount of bound water. […]
Large pore volume pseudo-boehmite is a type of pseudo-boehmite product characterized by a relatively large pore volume. For some catalyst support and industrial alumina applications, a larger pore volume can provide more sufficient internal pore space, so large pore volume pseudo-boehmite has attracted the attention of many industrial customers. However, it should be noted that […]
Many buyers usually focus first on price, Al₂O₃ content, and specific surface area when selecting pseudo-boehmite. However, there are many other factors that can have a real impact on subsequent processing and the performance of the final product, such as pore volume, pore size distribution, impurity content, particle size, moisture content, and batch-to-batch consistency. So, […]
A catalyst support needs to meet several requirements, such as having an appropriate pore structure, a large surface area, good thermal stability, and certain mechanical strength. Pseudo-boehmite can provide a good foundation for these properties. Large Specific Surface Area One important role of a catalyst support is to provide sufficient loading space for active components.
