The composite powders of CaB6 and boride (CaB6-LaB6, CaB6-ZrB2, CaB6-B4C and ZrB2-B4C) were synthesized by carbothermic reduction under induction heating conditions; the calcium boride and boride composite powders were introduced into the I

Ultra High Temperature Ceramics (UHTCs) are good choices for several extreme applications: thermal protection materials on hypersonic aerospace vehicles or re-usable atmospheric re-entry vehicles, specific components for propulsion, furnace

The technology for separation of zirconium and hafnium is the key to prepare nuclear grade productions of zirconium and hafnium. Zirconium and hafnium are normally associated together in nature (m(Hf)/m(Zr+Hf) is 1%3%) and difficult to sepa

The design of hypersonic flight vehicles is characterized by stringent requirements like achieving sharp leading edges to maximize lift-to-drag ratios while experiencing extreme external gas temperatures, which can reach upwards of 10,000K.

With the rapid development of science and technology, aircraft such as long-range missiles, rockets, space shuttles, spaceships and supersonic aircraft are developing in the direction of higher speed, greater thrust, higher altitude and more

Hafnium Silicide (HfSi2) is a transition metal silicide, a type of refractory intermetallic compound. Because of its unique physical and chemical properties, it is used in cermets, high-temperature oxidation-resistant coatings, high-temperat

Particle shape: During the preparation of metal powder, the powder particles will show different shapes according to different preparation methods, such as spherical, nearly spherical, polygonal, porous sponge, dendritic and so on. The part

Ultrafine ZrB2 powders were successfully synthesized by using a novel method that combines the sol–gel process with the rapid synthesis of spark plasma sintering (SPS).
