Porous materials are widely used in many fields. Microcellular molecular sieves, as primary catalytic materials, adsorption separation materials, and ion exchange materials, play an increasingly important role in petroleum processing, petrochemical industry, fine chemicals, and daily chemicals.
Molecular sieves, also known as synthetic zeolites, are a type of aluminosilicate microporous crystals. They consist of a basic framework structure made up of silicon oxygen and aluminum oxygen tetrahedra. Within the crystal lattice, metal cations such as Na+, K+, Ca2+, Li+ etc. are present to balance the excess negative charges in the crystal. Molecular sieves are mainly classified into different types based on their crystal structure: type A, type X, type Y, etc.

Product Introduction: Activated alumina, also known as active bauxite, is commonly referred to as "activated alumina" in the use of alumina as a catalyst. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface possesses the characteristics required for catalysis, such as adsorption properties, surface activity, and excellent thermal stability. Therefore, it is widely used as a catalyst and catalyst carrier in chemical reactions. High-performance activated alumina can bring the following benefits in the composition of amorphous refractory materials: increased density, fluidity, and strength of the matrix, increased production of secondary mullite, and reduced water content and porosity. In addition, activated alumina can also be used as a desiccant, with high water absorption and fast drying speed, and can be regenerated by baking at 400-500K.
Activated alumina belongs to the category of chemical alumina and is mainly used as an adsorbent, water purifier, catalyst, and catalyst carrier. Depending on the application, its raw materials and preparation methods vary. Activated alumina (molecular formula Al2O(3-x)(OH)2x, 0＜x＜0.8) is one of the widely used inorganic chemical products in the world. Due to its porous structure, high specific surface area, and unstable transition state, activated alumina has significant activity. In the petrochemical and fertilizer industries, it is extensively used as a catalyst and catalyst carrier. Activated alumina also has adsorption properties, making it used as a desiccant for gases and liquids, an adsorbent for gas purification, a fluoride removal agent for drinking water, and a substance for eliminating the color and odor of industrial wastewater. The main industrial activated alumina products today are produced by rapid dehydration methods. Activated alumina refers to calcined alumina with α-Al2O3 as the basic component, finely ground to a size of 1μm, accounting for 20%-90% of the total.

The nano-aluminaXZ-L14 appears as a white, fluffy powder. Its crystal form is alpha-type. The particle size is 20nm; the specific surface area is ≥50m²/g. It has a uniform particle size distribution, high purity, high dispersion, and is alpha-Al2O3. It has a low specific surface area, is inert under high temperatures, but does not possess catalytic activity. It is highly heat-resistant, has good formability, stable crystal phase, high hardness, and good dimensional stability. It can be widely used in strengthening and toughening various products such as plastics, rubbers, ceramics, and refractory materials. In particular, it significantly improves the density, smoothness, thermal fatigue resistance, fracture toughness, creep resistance of ceramics, and the wear resistance of polymer materials. Since alpha-alumina is also an excellent far-infrared emitting material, it is used as a far-infrared emitting and insulating material in chemical fiber products and high-pressure sodium lamps. Additionally, alpha-alumina has a high resistance and good insulation properties, making it suitable for use in the main components of YGA lasers and integrated circuit substrates.
