Pagination or Media Count:
Pressureless sintered silicon nitride has several favorable features and properties which make it a promising candidate for radome materials. First of all, pressureless sintering provides relatively unlimited shape forming capabilities. Process can be controlled reproducibly. Parts can be made relatively inexpensive. Pressureless sintered silicon nitride provides some excellent physical and mechanical properties which approach hot pressed silicon nitride.
