Unleash Ultimate Purity and Performance With Alumina Powder

Alumina (with the chemical formula Al2O3) is an extremely versatile industrial material, used in applications ranging from ceramics and abrasives to catalyst carriers. Our High Purity Alumina Powder is ideal for semiconductor leading-edge devices that demand exceptional etch purity and performance, as well as other critical applications requiring low levels of contamination and superior wear resistance.

High Purity

Alumina is an integral material used in many high-performance applications, yet the performance of ceramic alumina products depends on how pure they are. Utilizing high purity alumina (HPA) guarantees ceramics contain minimal contaminants/impurities for better thermal management and enhanced RF applications.

HPA is produced by dissolving and purifying aluminium hydroxide as the raw material, followed by calcination for higher levels of purity. This process is repeated repeatedly until desired purity levels are attained resulting in an alumina powder with many desirable characteristics such as chemical stability, high melting point, mechanical strength and hardness.

High Thermal Conductivity

Spherical alumina powders possess exceptional thermal conductivity, making them the ideal material for use as conductive pads and sheets in electronic devices. Their excellent temperature contact and dissipation capabilities help prevent overheating as well as equipment failure due to overheating.

Alumina powders boast consistent particle size distribution, making them suitable for various polishing applications and helping control polishing rates for uniform surface removal. Alumina’s versatility also makes it a must-have component in various high-performance ceramic applications like filtration systems and additive manufacturing.

Alumina powder can also be used to coat metal substrates and provide excellent heat dissipation in electronic modules and devices, like electronic modules and devices. Alumina is often used as an excellent thermally conductive coating material for printed circuit boards and integrated circuit packages due to its high thermal conductivity as well as low melting point and vapor pressure – meaning it can tolerate higher operating temperatures required by these coatings.

Excellent Wear Resistance

Alumina’s uniform-sized abrasive particles allow for controlled polishing rates and smooth surfaces, as well as making it an ideal material for advanced technical ceramics used across industries like aerospace, automotive and consumer products processing. Applications of Alumina ATCs include deburring, polishing scale removal mold cleaning pretreatment metal sandblasting.

The purpose of this study was to enhance wear resistance in alumina ceramics using trace amounts of Gd2O3. Alumina powder containing different percentages of Gd2O3 were prepared, then evaluated according to Chinese industry standard in terms of bulk density, particle size distribution, morphology and grain boundary cohesion before measuring wear rate according to Chinese standards. Results demonstrated that adding Gd2O3 had positive impacts on phase transitions, narrowed grain boundaries and enhanced binding forces between adjacent grains resulting in significantly improved wear resistance from alumina ceramics compared with previous designs; wear rates increased as Gd2O3 content increased parabolically with each additional percentage increase incorporated.
