Spherical Alumina Spherical alumina is produced through high temperature melt injection. This produces a high rate of spherical growth, high alpha-phase aluminum oxide content and superior performance in rubber, plastic, and ceramic materials. Trunnano Here is an overview of each method for preparing spherical-grade alumina. Here are seven different ways… Continue reading
What does nanopowder mean? Nanopowder Nanoparticle is commonly used to refer to extremely fine particles that are between 1-10 nm in size. Ultrafine particles are sometimes used to describe it. This scale is smaller than those of ordinary particles and atomic clusters. Through the outer layers of skin, lungs, and… Continue reading
Colloidal Gold A sol- or colloidal suspension made of small amounts of gold nanoparticles and dissolved in fluid (usually water). The most common colloids are wine red for spherical nanorods and smaller spherical pieces less than 100nm. Blue/purple is used to make larger spherical or rod-shaped particles. The optical, electronic… Continue reading
