METODO PARA PREPARAR FORMAS SINTERIZADAS,ARTIGO SINTERIZAVEL E FORMA SINTERIZADA |
摘要 |
<p>The invention relates to methods of preparing sintered shapes (shaped articles) 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 an amine other than an alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent or alkylalkyleneglycolacetic acylating agent; provided the reaction product is other than an alkylene oxide treated fatty monocarboxylic amide and provided that when the hydrocarbyl-substituted carboxylic acylating agent is a nonaromatic acylating agent, then the hydrocarbyl group is other than hydrocarbyl groups having an average of about 55 to about 110 carbon atoms; and sintering the green body. Sintered shapes obtainable from the methods of the present invention have relatively high fired densities and small uniform grain sizes and low porosity.</p> |
