Applications of cerium oxide sputtering targets

Electronics: In semiconductor manufacturing, it is used to prepare insulating films with a high dielectric constant (high – k). the high dielectric constant of Cerium oxide films can effectively reduce the capacitance size in integrated circuits and improve the integration and performance of devices.

Optical field: as an important material for optical films, it is used in the manufacture of infrared optical devices, such as windows of infrared detectors and infrared filters.

Energy field: In solid oxide fuel cells (SOFC), Cerium oxide plays an important role as a component of electrolyte materials or electrode materials.

In the field of automobile exhaust gas treatment: Cerium oxide has good oxygen storage capacity, and is used as a catalyst additive or carrier in automobile exhaust gas catalytic purification system.

Packaging and Storage

Cerium oxide targets are typically packed in vacuum-sealed bags or anti-static plastic bags, with additional cushioning such as foam or sponge to prevent collision and scratches during transportation. The outer packaging should indicate the product name, specifications, batch number, and handling instructions for proper transport and inspection.

Cerium oxide targets should be stored in a dry, ventilated, and cool warehouse, avoiding direct sunlight, high temperatures, and humid conditions. They should be kept away from corrosive chemicals such as acids and bases, and the packaging should remain intact to prevent dust or contaminants from affecting the target surface, ensuring stable performance.
