Alumina ore, (Al2O3) is mainly use (about 90%) in the manufacturing of metallic aluminum and only about 10 percent of alumina is used in non-metallurgical application such as high purity alumina.

Based on the various application of high-purity alumina the market can be categorized into four broad segments namely LED applications, semiconductor applications, phosphor applications, and other applications.

Based on the level of purity of the alumina the global high purity alumina market can be classified under three different quality standards namely, 4N (99.99% pure), 5N (99.999% pure) and 6N (99.9999% pure).

In high-purity alumina manufacturing, adulteration such as silicon, copper and iron are removed from the alumina to get desire level of purity of the alumina. Moreover alpha emitters such as thorium and uranium are also removed to certain level in order to obtain the enhance performance benefits such as low impurity levels, high conductivity, higher brightness and optimal processing characteristics.

High purity alumina offers various performance benefits over its traditional counterparts such as alumina. Properties such as enhanced hardness, higher corrosion resistance, and high level of brightness is making it as a prefer choice for various industries and a wide range of application which include semiconductors (such as tablets, computers, memory storage devices and smart phones), phosphor (such as plasma display), manufacturing of batteries (such as lithium-ion batteries), and automotive sensors.

The high cost of production of high purity alumina owing the high energy consumption in manufacturing high purity alumina coupled with lack of skilled labor resulting high labor cost in various developing countries of the world is acting as a major challenge for the global high-purity alumina market.

Asia Pacific is the largest market of high-purity alumina attributed mainly to the high concentration of allied industries such as semiconductor and electronics equipment manufacturing industries in China, Taiwan and South Korea. It is then followed by North America and Europe. The U.S is the largest regional market of high-purity alumina in North America, Germany, Italy and The U.K are the largest market of high-purity alumina in Europe. Asia Pacific region is also the fasted growing market of high-purity alumina driven mainly by the rising demand of high definition television, smart phones, and rising application of electronic sensors and display in automotive in this region.
