    Abstract: Curable compositions of matter comprising an epoxy resin and a curing agent selected from the group consisting of polyvalent metal salts of a phosphorodithioic acid, the acid being derived from the reaction of a phosphorus sulfide with a hydroxyl containing aromatic compound, and products derived from the reaction of the polyvalent metal salt with a mono- or polyamine.

    Abstract: The invention relates to a process for preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture comprising 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 compound 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 green body. Sintered shapes made from the compositions of the present invention have relatively high fired densities and grain sizes; and relatively low pore volume. (

    Abstract: 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.
