2454B Title: PROCESS FOR PREPARING SINTERED SHAPES AND COMPO- SITIONS USED THEREIN Abstract of the Invention The invention relates to a process for preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture compris- ing a major amount of at least one inorganic powder; and one or more additives selected from the group consisting of: (A) at least one reaction product of a hydroxy com- pound with a carboxylic acylating agent; (B) at least one Mannich reaction product; (C) at least one hydrocarbyl substituted amine; (D) at least one aminophenol; (E) at least one reaction product of a nitrophenol and amino compound; (F) at least one basic nitrogen-containing polymer; (G) at least one carboxylic acylating agent; (H) at least one aromatic acid or derivative thereof; (I) at least one aromatic oxime; and (J) at least one overbased or gelled overbased metal salt of an acidic organic compound provided that when the carboxylic acylating agent is a hydrocarbyl-substituted carboxylic acylating agent and the hydrocarbyl group contains less than an average of 40 carbon atoms, then the carboxylic acylating agent is a polycarboxylic acylating agent; and (2) sintering the body. Sintered shapes made from the compositions of the present invention have rela- tively high fired densities and grain sizes; and relatively low pore volume.
