.... Further, this powder gives off 25% of its mass during sintering due to evaporation of retained impurities. Such nanoscale powder is hazardous. Once dispersed in air, the powder remains suspended, which can create an explosion hazard. If inhaled, serious concerns arise over toxicity or long-term...
