Product Description
High Purity Alumina Powder
We adopt self-owned purification techniques and strictly control raw materials and production processes. The high purity alumina powder we produced have merits like high purity and high density, etc., which can be used for production of large-sized sapphire crystals with kyropoulos method, palpating method, TGT method, pulling method, etc. It is mainly used for sapphire crystals, laser crystals, and PDP fluorescent powder.
The product’s detailed specifications are as below:

Note: Grain sizes are adjustable as per clients’ requirements.
We mainly produce 5N, 5N5-6N5 ultra pure aluminum and aluminum alloy materials, and what’s worth noting is that we are the first in China to successfully develop and produce 6N5 ultra pure aluminum. We are capable of producing 1,200 tons of high purity aluminum annually and can provide round ingots, slab ingots, sections of high purity aluminum of various dimensions such as 30-Φ450mm and 1070×380mm, as well as cast ingots, targets and sections of aluminum alloys as per our clients’ requirements.
