ABSTRACT:
The present invention provides compositional buffers for electronic ceramics containing volatile elements, and a method for manufacturing and using the same. The surfaces of the fine crystal grains that make up an electronic ceramic such as a bismuth-based laminar compound or lead-based perovskite compound containing highly volatile cations such as bismuth or lead, or a thin film thereof, are covered compositional buffer composed of a silicate- or borate-based compound that readily forms an amorphous structure, and also provided is a method for manufacturing an electronic ceramic using the compositional buffer.
