News Release Details

BOSTON, MA (September 13, 2002) - Cabot Corporation announced today that it is exploring strategic alternatives to maximize value for its barium titanate business. Currently, Cabot's barium titanate business includes several product lines, a manufacturing facility, and a portfolio of intellectual property, including patents relating to compositions and other technology for use in the multi-layer ceramic (MLC) capacitor market. Barium titanate, or BaTiO3, is the predominant ceramic dielectric material in MLC capacitors and is now also finding application in the emerging Embedded Decoupling Capacitor (EDC) market.

Cabot has developed a proprietary hydrothermal process that allows for the manufacture of fine barium titanate products for MLC and EDC applications. Cabot has also developed a unique process for coating these and other particles with dopants for applications including high performance MLCs containing base metal electrodes. These technologies are targeted toward the continuous advances being made in the efficiency and miniaturization of capacitors.

"The superior properties of Cabot barium titanate bring high performance to both MLC and emerging EDC applications, said Dr. Stephen Costantino, Managing Director, Advanced Capacitor Materials, Cabot. "We have also demonstrated commercial-scale capability for coated powders in our manufacturing facility. Our barium titanate business holds strong potential and the examination of all alternatives for future growth will be beneficial to shareholders and customers."
