N2 - Fiberlike Si3N4 was prepared by the carbothermal reduction of diatomaceous earth in a flow of nitrogen and ammonia. Diatomaceous earth, which is an inexpensive raw material, is composed of 82.5 wt% SiO2, 5.69 wt% Al2O3, and a very small amount of metal oxides (K2O, CaO, and Fe2O3). Two types of fiberlike Si3N4 were obtained, short needlelike fiber and woollike fiber with Fe droplets at 1350°C.
