摘要： Complex greases of overbased alkaline earth metal carboxylates are prepared by reacting an overbased alkaline earth metal salt of a fatty acid, wherein the alkaline earth metal salt has an alkaline earth metal content of at least 14.5% and a non-volatile matter content of at least 95% with conversion agents to form a grease precursor. The grease precursor is then reacted with complexing agents to form a predominantly vaterite containing non-Newtonian modified overbased metal carboxylate complex grease.

摘要： An iron-base powder mixture containing an iron-base powder, a lubricant having been fused and adhered to the iron-base powder, a powder for an alloy adhered to the iron-base powder through the lubricant, and a free lubricant powder, characterized in that one or more of the above iron-base powder, the above lubricant having been fused and adhered to the iron-base powder, the above free lubricant powder, and the above powder for an alloy have a surface which is coated with an organosiloxane with a covering percentage of 80 % or more; and a method for producing the iron-base powder mixture. The iron-base powder mixture is excellent in flowability and formability, and also is reduced in the temperature dependency of flowability and green density. It is preferred that the organosiloxane has a phenyl group, the lubricant having been fused and adhered to the iron-base powder is a co-molten product of a calcium soap with a lithium soap or a co-molten product of a calcium soap with an amide lubricant, and the free lubricant is a lithium soap or a mixed powder of an amide lubricant with a poly(methyl methacrylate) powder.
