2014 - 2019 Global Alumina Market Increase Nearly 28%- Tungsten Crucible Made Sapphire Market Broaden

According to international market research report, in 2014-2019, the global high purity alumina market compound annual growth rate will increase nearly 28%. As we known, alumina often referred to as smelter grade alumina (SGA) primarily because it is often used as a raw material for producing aluminum. Alumina mainly be used for aluminum process, only 10% for non-metallurgical alumina market, namely for industrial use.

High purity alumina refers to the minimum purity of 99.99%, and it is high-end products of non-metallurgical alumina market. High purity alumina is a white powder having uniform and easy dispersion particle, stable chemical property, moderate high-temperature shrinkage, good sintering property, high conversion rate, low sodium content and other good property. It is raw material for heat, wear and corrosion products production. Currently, it is used in LED, semiconductor, phosphor, sapphire crystal preparation and other fields.

Alumina as raw materials for sapphire single crystal oxide production, with sapphire single crystal applications broaden, the alumina market demand is also growing. Tungsten crucible made sapphire single crystal applications currently on the market are as infrared transparent window materials, microelectronics substrate body, laser matrix, optical components and other purposes.

A study shows sapphire crystal as LED substrate material benefits from the rapid development of LED lighting systems market demand having further expansion, which makes the market demand of sapphire single crystal raw material alumina also having a greater degree of expansion. In 2015 alumina demand growth rate reached 16%. In addition, sapphire crystal applications in the smart phone, making the alumina in this area the growth rate reached 20%. If consider the future use in the mobile phone market, the future demand for alumina and sapphire crystal equivalent to the current needs of the tens times.
