Low pressure laminated ceramic devices and method

A method of forming intermediate low-pressure laminated ceramic devices comprising the steps of:

• providing a plurality of layers of unfired ceramic material each including ceramic particles in an organic binder;
• depositing a polymer interfacial layer on one surface of each of the plurality of layers of unfired ceramic material, the polymer interfacial layer having a glass transition temperature such that the polymer interfacial layer flows at a temperature below a temperature required for the plurality of layers of unfired ceramic material to substantially deform;
• stacking the plurality of layers of unfired ceramic material in overlying relationship to form a stack with a polymer interfacial layer positioned between adjacent unfired ceramic layers in the stack;
• heating the stack to a temperature greater than the glass transition temperature of the polymer interfacial layer;
• and
• applying a pressure to the heated stack below approximately 1200 psi to fixedly bond the plurality of layers in the stack together.
