Isostatic pressing graphite product with high strength and high density has higher mechanics performance, machinery performance and good processing performance. It is widely used in metallurgy industry, semi-conductive industry, spark processing, biological material, nuclear industry, aerospace industry, national defense and military industry, etc. It has higher economic benefit and strategy significance. Therefore, every country is focuing on studying this aspect. At present, the study of isostatic pressing graphite product with high strength and high density from America, Japan, Germany, France, Russia and other countries rank leading position with good product performance and various kinds. Our country still has a great gap compared with these countries. Mainly shows below:
Weak basic research. There are many factors for isostatic pressing molding, such as material selection, granules composition, moulding pressure, roast temperature, heating rate of graphitization and heat treatment temperature, etc. There is no systematic and comprehensive studies on these factors.
Poor product performance. Our carbon industry has a great gap with America, Japan, Germany, France and other countries, especially in mechanical performance.
