spontaneous gelation breaks through the key bottleneck problems such as deformation and cracking of large-size ceramic wet billets during drying, and produce large-size high-purity alumina ceramic grinding discs with diameters of 360mm to 600mm, 1400x900x30, 500x500x45, 1180x490x20mm etc . Large-scale structural ceramic parts have a wide range of applications in Semiconductors Manufactur, LCD Equipment, General industrial Machines and other fields, but the molding of large-scale ceramic parts is extremely challenging. Compared with classic cold isostatic pressing and injection molding, gelcasting (gelcasting, or gel injection molding) has outstanding advantages: the green microstructure is uniform, fundamentally ensuring the reliability of ceramic components; The billet has high strength and density, is convenient to handle, and can effectively reduce the risk of sintering shrinkage and cracking; near-net-shape molding can greatly reduce the machining cost. In addition, the inject...

Activated alumina ball, the name is Activated Alumina or Reactive alumina; activated alumin (I) um oxide. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required for catalysis, so it is widely used as a catalyst, fluoride adsorbent and desiccant. 1: Applied  as a desiccant Activated alumina desiccant is mainly used for drying liquids and gases. Although it can absorb all molecules to a certain extent, it will preferentially absorb molecules with strong polarity. Gas pressure, concentration, molecular weight, temperature and molecular active sites all affect the adsorption effect. Common sizes of activated alumina desiccant are spherical 1/16 ", 1/8", 3/16 ", 1/4". It is widely used for gas and liquid phase drying in petrochemical industry, for drying textile industry, oxygen industry and automatic instrument air, pressure swing adsorption in air separation industry, etc. Due to the ...

Filter tube The ceramic filter tube is composed of many uniform micropores. When the fluid passes through these tiny holes, suspended substances, colloidal particles, and macromolecular organic matter are trapped on the surface of the filter medium. The fluid passes through the microporous ceramic filter tube to produce various physical effects, achieving mechanical screening purification or diffusion, fluidization, etc. efficacy Product Features : 1: Good heat resistance, no thermal deformation, and the effect is unchanged at 500 ℃. 2: Excellent cold resistance and freeze resistance. 3: The micropores are evenly distributed, and various pore sizes below 500 μm can be formed according to user requirements. 4: Due to the high rigidity, it will not cause shape change and pore deformation under the action of fluid pressure, so that it is easy to remove slag and regeneration during product application. 5: There is no dissolved substance in the liquid, so the liquid wil...

                                      Application of inert alumina ceramic ball It has the characteristics of high mechanical strength, long service life, good chemical stability, no chemical reaction with materials, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, and good thermal shock stability. Because the chemical nature of the inert porcelain ball is relatively lazy, it obviously does not undergo chemical reactions throughout the reactor. Use a carrier to cover the catalyst without changing the catalyst. The gas or liquid in the reactor has a temperature. The filling above the ceramic ball prevents the gas or liquid from blowing directly to the catalyst, which has a protective effect on the catalyst control. The shape of the porcelain ball is conducive to the uniform distribution of gas or liquid. Promote a more complete chemi...

 Raw Material Importance to Advanced Ceramics “Raw materials are the foundation, molding is the condition, and firing is the key" is the experience that ceramic workers have summed up from many years of ceramic production practice. This shows the importance of raw materials in ensuring product quality. In order to produce high-quality ceramic products, it is important to choose the right raw materials, and the inherent characteristics of the raw materials themselves are the inherent basis to ensure that the products obtain the ideal quality. Obviously, the preparation method of raw materials deserves special attention. There are generally two types of preparation methods for raw materials used in ceramic products: one is mechanical crushing and fluctuation, and the other is synthesis. The former method is a method of crushing coarse particles to obtain fine powder by mechanical methods, which has the advantages of large production volume and low cost, but there are proble...

Ceramic is the oldest material, and it is the first chemical product made by human conquering nature. It appeared much earlier than metal materials. It is one of the symbols of human civilization and an important research object in the history of human civilization. For a long time, the development of ceramic materials relies on the teaching of craftsmanship. The products are mainly household utensils, building materials (such as bricks, glass), etc., usually called traditional ceramics. Due to the development of materials science, people have a deep understanding of the relationship between material structure and distribution. They can successfully control the chemical composition and micro - structure of lattice materials and successfully develop ceramic materials with different properties. For example, high-temperature structural ceramics and various functional ceramics (electronic materials, optical fibers, sensitive ceramic materials, etc.) have been more and more widely used, an...
