PREPARATION OF SINTERED MOLDED ITEM AND NON-SINTERED BODY USED FOR THEM

摘要

The invention relates to (1) a method of preparing sintered shapes, comprising the steps of forming a green body from a mixture comprising (A) a major amount of at least one inorganic powder with (B) at least one reaction product of a alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent provided that when the hydrocarbyl group of the acylating agent contains less than 40 carbon atoms then the carboxylic acylating agent is a polycarboxylic acylating agent; and (2) sintering the green body. Sintered shapes made from the methods of the present invention have relatively high fired densities and small uniform grain sizes and low porosity.
