The Benefits of High Purity Alumina

Haiwei Emerging Material is a company specializing in supplying of high purity alumina powder and special advanced alumina products. We strive hard to offer the first class quality products and best possible customer service and value and have set performance standards in every aspect of our business.

High Purity Alumina

Alumina is a chemical compound and aluminum oxide with a purity of 99.5% or higher. Alumina is usually processed by heating raw aluminum ore in an electric furnace to produce molten alumina, which is then purified by removing dross and other impurities from the surface.

Advantages of High Purity Alumina

High purity alumina has a number of advantages over traditional forms of alumina. It is easier to handle and produces less dust, making it more suitable for certain kinds of industrial processes. It also offers better corrosion protection, higher thermal conductivity, and lower density.

High Strength and Tough Properties

High purity alumina has high strength and tough properties. It has the highest strength and toughness of any ceramic materials. In addition, it is also more corrosion-resistant than aluminum metal.

Excellent Thermal and Electrical Conductivity

One of the most important properties of high purity alumina is its excellent thermal and electrical conductivity. Alumina is an extremely strong and durable material, which helps it resist abrasions, impact, heat and corrosion. High purity alumina has a melting point of 3,400 degrees Fahrenheit (1,898 degrees Celsius), so its excellent thermal conductivity means that it will melt at a lower temperature than other materials. The thermal insulation property also makes it possible to maintain a low temperature inside buildings during hot summer days. The electrical conductivity is up to five times higher than that of copper or aluminum. The resistance in the electric circuit and the dielectric constant are also much higher than those of copper or aluminum. Alumina’s advantages are endless.

Versatility in Many Applications

Alumina is an element that is used in many different applications. One of the main benefits of alumina is its versatility when it comes to contamination levels. Alumina has a high purity level, which means that contaminants can be kept at a low level. Normally, you’d have to use caustic chemicals to extract and remove impurities, but alumina can be done without those chemicals. This makes it easy and cost-effective for businesses who wish to produce any material with high purity levels. Alumina is able to withstand high temperatures without melting or cracking. Because of this quality, alumina can be found in things like stoves and ceramic tiles. Alumina also has excellent thermal stability properties, meaning it doesn’t change much when heated or cooled rapidly. In other words, if you need something for high temperature resistance and thermal stability, this is your go-to product!


High purity alumina has a number of benefits and is widely used in a variety of applications. It has a high strength and tough properties that make it ideal for many uses. The excellent thermal and electrical conductivity also make it perfect for many electrical and thermal applications. High purity alumina is a great material to have on hand.
