A technology for producing nanoporous ceramics based on mullite (3Al2O3 ⋅ 2SiO2) is developed. The mechanochemical activation of oxides involved in the synthesis of mullite (γ-Al2O3 and amorphous SiO2) makes it possible to obtain single-phase 3Al2

Defects in parts produced from metal powder by selective laser fusion are studied. Typical defects are presented for this method. They do not depend on the type of metal powder but rather on the chemical composition and purity of the initial material
