Ultrafine powders refer to materials with particle sizes ranging from the micron to nanometer scale. According to industry consensus in mineral processing, ultrafine powders are defined as powders with 100% particle size below 30 μm. Based on particle size, ultrafine powders are usually divided into three categories: micron scale (1–30 ...

Nanoceramics exhibit excellent performance when their nanoparticle distribution is uniform, sintering shrinkage is consistent, and grain growth is even. However, due to the small particle size and strong interparticle forces (such as electrostatic, van der Waals, capillary, and mechanical forces), nanoceramic powders tend to agglomerate, have poor flowability, and significantly ...

Xanthan gum appears as an off-white or light-yellow solid powder; it has a slight odor and no taste. In water, it swells into a colloidal solution but is insoluble in ethanol and organic solvents (such as acetone, ether). Xanthan gum dissolves easily in both cold and hot water, forming solutions ...

Silicon carbide (SiC) micro powder is a high-performance structural ceramic material. It features high density, thermal conductivity, bending strength, elastic modulus, and excellent resistance to corrosion and high temperature. Because of these properties, it is widely used in industries with demanding structural requirements. From Reaction Sintering to Recrystallization: Particle Control ...

Silica micro-powder is an inorganic non-metallic functional powder material. It has unique physical and chemical properties such as high heat resistance, high insulation, low linear expansion coefficient, and good thermal conductivity. It is widely used in copper-clad laminates, epoxy molding compounds, electrical insulation materials, adhesives, ceramics, and coatings. It also ...

There are various methods for ultrafine powder surface modification, generally categorized into: surface coating, surface chemical modification, mechanochemical modification, capsule-type modification, high-energy modification, and precipitation reaction modification. Surface Coating Modification Ultrafine powder surface coating modification involves the use of surface modifiers that do not chemically react with the particle surface. ...

Ultrafine nickel powder generally refers to nickel powder with a particle size of less than 1 μm. According to particle size, ultrafine nickel powder is usually divided into micron-grade nickel powder (average particle size ≥ 1 μm), submicron-grade nickel powder (average particle size 0.1–1.0 μm), and nano-grade nickel powder (average ...

Silica micro-powder, as a typical inorganic filler, possesses excellent properties, including: During the ultra-fine grinding process, the specific surface area of silica micro-powder increases continuously. As a result, large amounts of hydroxyl groups (-OH) are exposed on the surface, enhancing its polarity. This results in higher surface energy, and due ...
