Aluminum oxide ceramics have various important applications in the military industry, mainly reflected in the following aspects:

Bulletproof armor: Alumina ceramics are often used as part of bulletproof armor materials due to their high hardness and wear resistance. In military equipment such as vehicles, airplanes, and ships, armor with alumina ceramic layers can effectively reduce the impact force of bullets or shells, protecting the safety of personnel and equipment inside the vehicle.

Missile guidance components: Alumina ceramics are often used as materials for missile guidance components due to their high thermal and chemical stability. The guidance components of missiles need to maintain stable performance in high-speed flight and high-temperature environments, and alumina ceramics can meet these requirements.

Aerospace components: In the aerospace field, alumina ceramics also have important applications. For example, it can be used as a nozzle for rocket engines, insulation material for missiles, thermal protection layer for spacecraft, etc., because it has excellent high-temperature stability and wear resistance.

Electronic devices: Alumina ceramics are often used as substrate materials for manufacturing military electronic devices. Its excellent insulation performance and chemical stability can protect electronic components from external interference and damage, ensuring the normal operation of the equipment.

Communication equipment: In the field of military communication, alumina ceramics are also used. For example, it can be used to manufacture components such as antennas, microwave devices, RF filters, etc., to ensure the efficient operation of communication equipment and the security of data transmission.
