Ceramic ferrules are typically made from materials that can withstand high temperatures and offer good mechanical stability. The two oxides commonly used for manufacturing ceramic ferrules are aluminum oxide (Al2O3) and zirconium oxide (ZrO2).

Aluminum oxide is well-regarded for its strength and durability, making it an ideal choice for applications involving optical fibers, where precision and longevity are crucial. Zirconium oxide is also favored for its thermal and chemical stability, enhancing the overall performance of the ferrule process. When combined, these oxides provide the necessary properties for effective fiber optic connections, such as low insertion loss and high resistance to environmental factors.

The other options consist of materials that do not have the same level of appropriateness or performance characteristics for ceramic ferrules used in fiber optics. For example, silicon is not typically utilized in ferrule construction due to its different physical and chemical properties, and materials like titanium and lead do not provide the same advantages as aluminum or zirconium oxides in this specific application.
