Abstract
A process and apparatus are provided for preparing a release layer suitable for facilitating release of green ceramic laminates from a lamination fixture. The process comprises applying an electrostatic charge to at least one variably electrostatically chargeable portion of at least one lamination fixture and dispensing a layer of ceramic particulates, glass particulates or glass-ceramic particulates onto the charged portion of the lamination fixture to form a release layer on the lamination fixture. The apparatus provides a particulate dispenser for dispensing a layer of particulates of ceramic, glass, or ceramic-glass mixture, at least one lamination fixture having at least one variably electrostatically chargeable portion disposed in particulate receiving communication with the particulate dispenser; and a variable voltage electrostatic generator in electrical communication with the at least one chargeable portion of the lamination fixture.
