Description

Technical Field

[0001] The utility model relates to the technical field of ceramic components, in particular to a plasma-resistant aluminum oxide ceramic component. Background Art

[0002] Alumina ceramics, a ceramic material primarily composed of aluminum oxide, exhibit excellent conductivity, mechanical strength, and high-temperature resistance. They are widely used in thick-film integrated circuits and other high-tech fields. Currently, alumina ceramics are often used as containers. Due to their stable properties and excellent protective properties, alumina ceramics are often used to store items such as paper.

[0003] In order to ensure the sealing of the components, reduce the gaps at the openings where outside air can enter and cause oxidation to the stored items, and thus play a role in plasma resistance, most of the existing ceramic containers can only be opened through a single sealed door. When placing ceramic containers, in order to improve space utilization, multiple containers are often stacked.

There are certain limitations in placement, which reduces the stacking efficiency of alumina ceramic components. If it is later discovered that the ceramic components have been placed in the wrong orientation, a lot of time will be required to readjust the position, which brings a lot of inconvenience to storing and retrieving items.
