摘要： A producing method of a porous Si3N4 having high porosity and formed of Si3N4 particles having a high aspect ratio includes the following steps. A compound of a rare earth element as a first sintering agent is mixed in an amount of 7.5-45 parts by mass, in terms of an oxide of the element, with respect to 100 parts by mass of Si powder to obtain mixed powder. A binder is added to the mixed powder, which is then molded into a molded body. The molded body is heated in a nitrogen atmosphere to 300-500null C. to remove the binder. The binder-removed body is heated in a nitrogen atmosphere to 1350-1500null C. for nitriding. The nitrided body is then sintered at 1750-1900null C. at a nitrogen pressure of 0.1-1 atmosphere.

摘要： A Ca—SiAlON ceramic with enhanced mechanical properties and a method employing micron-sized and submicron precursors to form the Ca—SiAlON ceramic. The Ca—SiAlON ceramic comprises not more than 42 wt % silicon, relative to the total weight of the Ca—SiAlON ceramic. The method employs submicron particles and also allows for substituting a portion of aluminum nitride with aluminum to form the Ca—SiAlON ceramic with enhanced mechanical properties.
