The most commonly utilized oxide ceramic material is alumina (aluminum oxide). Tap washers, spark plugs, abrasion-resistant tiles, and cutting tools are just a few of its numerous uses. Additionally, the production of brick and monolithic refractories uses very high tonnages. Sliding gate and pouring spouts valves are two further, more challenging uses that combine it with other materials such as flake graphite.
Abrasives
Numerous industrial abrasive compounds that are used to form industrial components extensively utilize alumina. This is mostly because of alumina's higher strength and hardness, which enable it to function in various tools and applications. It's interesting to note that the roles may also be switched around, with alumina serving as a coating to prevent abrasion from other industrial products.
Refractories
Alumina powder is frequently used in refractory materials due to its thermal capacity and high melting point. Alumina is particularly helpful in circumstances when the refractory's strength must be maintained at high temperatures. Refractories are used in processes including creating iron and steel, cement, waste incineration, and petrochemical processing.
Glass
Adding alumina to the design and manufacturing of glass items is a terrific idea, especially when more durability and strength are required. Glass that is bulletproof and shatterproof is frequently produced with alumina powder. Alumina has also been investigated for its capacity in the development of fully indestructible glass, even though this is an impossible feat.
Ceramics
Alumina powder is often used in ceramics, especially in "engineered" ceramics, which are more sophisticated or technically sophisticated. These substances have been developed for very demanding applications that need thermal stability, higher wear resistance, and many other properties that make alumina such a desirable component of so many products.
Medical Industry
Alumina is a favored material for many biomedical applications due to its hardness and advantageous chemical characteristics. Alumina is utilized in a variety of bionic implants, dental implants, prosthetic eye replacements, prosthetic limb bearings, and prosthetic hip replacement bearings. It is also utilized outside of the body in the medical sector in lab instruments and equipment such as furnaces, crucibles, and other labware.
