Dispersion of ultrafine SiC particles in molten Al-12Si alloy Jin-Ju PARK, Sang-Hoon LEE, Min-Ku LEE, Chang-Kyu RHEE Nuclear Materials Research Division, Korea Atomic Energy Research Institute... particles at very high combustion temperatures, producing the coarse Al particles (several tens of microns) containing ultrafine SiC ceramic particles. Microstructural observation revealed......
in the solution, the hollow spheres are formed. The higher the alkali content, the more the ultrafine colloidal cores. Key words: ultrafine particles; core-shell; self-sacrifice; morphology 1 Introduction Ultrafine particles stand for granules with diameter less than 0.5 ?m. For their extremely small size and large specific surface area, these sub-micron powders can be widely used as catalysts......
