Advantage of Alumina Ceramic

Recently updated

Alumina ceramic is one of the hardest and strongest advanced ceramic materials available, offering exceptional hardness, corrosion resistance, strength at both room temperatures and elevated temperatures.

No interaction exists with oxygen, chlorine and sulfuric acid (hot). It can be made into refractory materials, furnace tubes, glass drawing crucibles and thermocouple protective covers.

High Hardness

Alumina is a hard engineering ceramic material with exceptional resistance to abrasion, wear and corrosion. It can be formed into various shapes to fit various applications and is also very machinable. Furthermore, Alumina boasts low thermal expansion properties so as to withstand high temperature exposure; furthermore its chemical stability makes it suitable for non-lubricated areas.

Alumina (Al2O3) is one of the most frequently utilized technical ceramic grades. It comes in various purity levels ranging from 94% for metallizability purposes up to 99.8% purity levels suitable for high performance applications. Purity levels influence its properties such as electrical insulation, high chemical resistance and good thermal stability.

High-purity alumina can be processed into various technical ceramics, the most prevalent being refractory furnace tubes, special crucibles and ceramic bearings. Furthermore, its wide array of applications extends to cutting tools, nozzles and friction components used by piston engines and machinery as it boasts exceptional strength and wear resistance that surpasses silicon carbide's.

High Insulation

Alumina ceramic's insulation properties make it a suitable material for high-voltage bushings and components that require hermeticity (vacuum tightness) for transmitting power or fluids, such as hermetic seals for high voltage bushings or components that use hermeticity to transfer fluids or power, or thermal barriers to reduce heat loss. As purity of alumina ceramic increases, its insulation qualities improve, making it an excellent choice for electrical applications.

Alumina ceramic is dense, which results in its low coefficient of expansion when exposed to heat, providing resistance against thermal shock while still remaining robust enough for extreme conditions and temperatures.

Sturdiness makes ceramic an ideal material for producing technical ceramic parts such as refractories and engineered shapes such as disks, rings, or rectangles - using custom injection molding processes, ceramic manufacturers can produce exact specifications and tolerances required by certain components.

Manufacturers employ fine particle grinding of alumina material in order to produce ceramic products with optimal wear properties, producing ceramics with reduced porosity and higher wear resistance and tensile strength. Alumina ceramic components used in total knee replacements (TKRs) protect against stress-related creep, increasing wear resistance. It may even improve long-term knee performance and clinical outcomes by providing better protection from stresses or stresses creep of implant.
