What are the main materials of oxide ceramics

       Oxide ceramics are commonly used ceramic coating materials. According to its composition classification, there are mainly alumina series, oxides, zinc oxide, chromium oxide, mullite, spinel ceramics, etc.

    The melting point of oxides is very high, mostly above 2000 degrees Celsius. Most oxides are stable in an oxidizing atmosphere, and most oxides have electrical insulation and thermal insulation properties, and high strength in high temperature environments.

    The biggest feature of oxide ceramics in thermal spraying process is that it can be sprayed directly in the atmospheric environment without vacuum or protective atmosphere, which is of great benefit for equipment manufacturing, spraying workshop design and cost reduction. Therefore, oxide ceramics have become the most widely used and most used ceramic coating materials in thermal spraying technology.

    Oxide-based thermal spray ceramic coatings are widely used in chemical and metallurgical fields such as petrochemical and metal metallurgy using their corrosion resistance; machinery and conveying fields using their wear resistance; Aerospace engines with thermal barrier properties; and other functional coatings utilizing properties such as electrical insulation, magnetic shielding, solid electrolytes, and infrared radiation.
