The meanings of metamorphic treatment, grain refinement, and primary phase refinement or morphology change are different, and sometimes the term metamorphic treatment is used to summarize these contents. (1) Deterioration treatment. For simple binary Al Si alloys, such as Z102 containing 11%~13% Si, it is a typical eutectic alloy. Its organization consists of coarse needle shaped (should be layere...

With the increasing demand for high thermal conductivity materials, filled thermal conductive polymer composites have good application prospects. The performance of thermal conductive composite materials largely depends on the selection of thermal conductive fillers. Aluminum oxide (Al2O3)is a common ceramic filler with high hardness and good thermal conductivity, and is a commonly used choice to ...

Powder surface modification changes the surface state of particles through physical or chemical means, with the core being to break the agglomeration force between particles. When the particle size of the powder decreases to the micrometer or nanometer level, the surface energy sharply increases, and van der Waals forces, hydrogen bonds, and other gravitational forces cause the particles to sponta...

Why modify the powder? Inorganic powders have hydrophilic and polar surfaces, but poor compatibility with organic matrices (plastics, rubber, resins). Direct use can lead to poor performance, so modification is necessary. (1) Improve dispersibility and prevent agglomeration. Inorganic powders with a large specific surface area are prone to agglomeration, which can lead to defects and a decrease in...
