Our news journalists obtained a quote from the research, "These powders are fed through a plasma torch, where they are melted and actively quenched in flight with argon gas. Plasma processed powders are composed of crystalline B4C and TiB2, with some additional B2O3 oxide phase. The plasma processing method results in the production of monolithic B4C and TiB2 nanoparticles, but some larger particles (generally 10m in diameter) are shown to contain the traditional lamellar eutectic microstructure. The eutectic interphase spacing ranges from 100 to 650nm, and the composite microstructure is present through the entire thickness of the eutectic particles."
According to the news editors, the research concluded: "Future work on plasma processing of eutectic powders should focus on methods utilizing passive in-flight quenching to increase the average particle size."
