ABSTRACT:
This invention provides a multi-step process for the preparation of ceramic fibers, such as ferrimagnetic spinel fibers which are useful in electromagnetic interaction shielding applications.
The process involves subjecting a ceramic powder-filled hollow organic fiber to isostatic pressing, and then pyrolyzing and sintering the compacted fiber to yield a ceramic fiber.
