Aluminium Oxide Ceramic Powder

We can tailor a complete coating system for your specific needs with our flexible and expert resources.

Aluminium oxide ceramic powder.

This aluminium oxide or alumina powder is often mixed with an organic binder to help it keep its desired shape before it is fixed. Aluminium oxide abrasive grit classic brown abrasive grit used with coldax cement and blasting machines. It is commonly called alumina and may also be called aloxide aloxite or alundum depending on particular forms or applications. Alumina or aluminum oxide al 2 o 3 in its various levels of purity is used more often than any other advanced ceramic material.

The traditional ceramics that we recognise from our kitchens are objects made of clay and cements that have been hardened by heating at high temperatures whereas advanced or engineered ceramics like this one are made by sintering fine powders of pure chemical compounds formed between metallic aluminium and non metallic oxygen elements such as aluminium oxide or metalloid silicon and non metallic carbon elements such as silicon carbide. Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. Examples of applications for aluminum oxide al 2 o 3 advanced ceramics are heavy duty forming tools substrates and resistor cores in the electronics industry tiles for wear protection and ballistics thread guides in textile engineering seal and regulator discs for water taps and valves heat sinks for lighting systems protection tubes in. There are both coarse and fine grained varieties.

Grades formats bonding types extremely high purity 99 9 alumina grades can be fabricated using a choice of bonding and forming techniques blending casting pressing etc to yield a high wear and corrosion resistant ceramic suitable for many applications. Examples include thermal or electrical insulation and wear and corrosion resistance. This moulded powder is then heated to a very high temperature in a controlled atmosphere until its individual particles fuse together and form chemical bonds sintering shrinking and hardening it into a dense. Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula al2o3.

Due to its outstanding properties alumina has contributed to a significant number of life extending and society enhancing applications. Aluminum oxide ceramics can subsequently service one of the broadest industrial cross sections of any oxide ceramic on the market. When sprayed this powder produces a hard dense coating that offers wear resistance dielectric strength in aerospace printing automotive chemical applications. It occurs naturally in its crystalline polymorphic phase α al2o3 as the mineral corundum varieties of which form the precious gemstones ruby and sapphire.

The most well known oxide ceramic material. Alumina commonly known as aluminium oxide al2o3 is an inert odourless white amorphous material often used in industrial ceramics. Oxide ceramic powder materials for thermal spray applying thermal sprayed ceramics onto metallic substrates offers enhanced surface properties. We stock a range for coarse grit such as 40 all the way upto micro fine grades such as 600 800 and 1200.
