Here are some websites that should be of help:
Metal Powder Industries Federation
“This website is the world's most comprehensive resource for information about Powder Metallurgy (P/M) and Particulate Materials. Here you will find details about the process and technology, design data and applications, resources for technical publications, standards, conferences, and seminars. Also covered is information on the P/M industry and its leading companies including suppliers of metal powders, powder metallurgy parts and products, processing equipment, consultants and academic/research institutions.”

The publications of PMAI are: PM news letters, Transactions of PMAI, proceedings of One Day Workshops, who's who in PM in India.”
TECHNICAL REPORT: Copper And Copper Alloy Powder Metallurgy Properties And Applications by John L. Everhart
Very thorough, everything you want to know. Includes useful appendices: Bibliography, Glossary, P/M standards.
Powder Metallurgy Equipment Association.
”PMEA members supply tools and dies, compacting presses, injection molding equipment, sintering furnaces and atmospheres, metal powder handling and impregnation equipment, furnace belts, mixing and QC equipment and other equipment and services used to make P/M parts and products.”
Hope this helps,
