Abstract
A method for preparing flat foils having a high density includes the steps of mixing a powdered material with a binder to form a green sheet. The green sheet is exposed to a high intensity radiative source adapted to emit radiation of wavelengths corresponding to an absorption spectrum of the powdered material. The surface of the green sheet is heated while a lower sub-surface temperature is maintained. An apparatus for preparing a foil from a green sheet using a radiation source is also disclosed.
Claims36
A method for preparing foils, comprising the steps of:
- mixing a powder composition with a binder to form a green sheet;
- exposing said green sheet to a plasma radiation source, said radiation source emitting directional radiation, said radiation adapted to heat said green sheet, wherein a heated foil is formed, and
- cooling said heated foil, wherein a foil including said composition is obtained.
An apparatus for preparing a foil from powder, comprising:
- a plasma radiation source adapted to emit radiation of wavelengths corresponding to an absorption spectrum of a green sheet which comprises a powder, said radiation source emitting directional radiation,
- structure for translating said green sheet relative to said plasma radiation source, wherein following exposure to said plasma radiation source a foil is obtained, and
- a process chamber.
A method for preparing foils, comprising the steps of:
- mixing a powder composition with a binder to form a green sheet;
- exposing said green sheet to a plasma radiation source, said radiation source being adapted to melt a surface of said green sheet while not melting a sub-surface portion of said green sheet, wherein a heated foil is formed, and
- cooling said heated foil, wherein a foil including said composition is obtained.
