Mechanochemical way to obtain ultrafine oxide and nitride powders with extremely high formability and sinterability has been developed. Low temperature pressureless sintering leads to dense ceramics with gain size within 0.1-0.2 µm.
A “glue” for diffusional welding of ceramics has been developed on the basis of α-Al2O3 nanopowder. Drying and firing conditions being properly selected, the strength of junction is competitive with that of materials to be sticked together.
