Sažetak
Aluminium oxide (A2O3) is the most important material from the group of oxide ceramics due to the extremely wide range of applications. The most important properties of aluminium oxide ceramics are high strength and hardness, temperature stability, high resistance to abrasion, resistance to aggressive work environment (except limited alkali resistance) and corrosion resistance at elevated temperatures. Due to these properties, aluminium oxide is used in the following areas: sanitation industry for sealing elements, electrical insulating parts, electronics substrates, engineering and construction of wear resistant parts, chemical industry for parts that are corrosion, high-temperature steam, and molten slag resistant, thermocouple measurements at high temperatures, medical implants and high temperature applications, such as nozzle and heater mounts. This paper describes the process of preparation of highly pure aluminium oxide (α-Al2O3) ceramics for extrusion moulding, quality comparable to the world market. The production includes the following operations: obtaining α-Al2O3, preparation of ceramic powders, preparation of ceramic mass, extruding, drying, sintering, product testing.
