The superiority of the Prima products

Our products are acknowledged and appreciated by eucosapphire manufacturers as well as other manufacturing companies using aluminum-containing powders. As compared to our competitors, we assess our product purity from 27 admixtures as contrasted to 6-8 admixtures accounted for by the majority of manufacturers. Even taking into account such strict requirements the powder purity is 99.9997% and higher, which is the best in the Russian market.

Several batches of our powder, together with products by other leading Russian and foreign manufacturers, were taken for comparative analysis of aluminum gamma oxide powder, carried out by Korund Ltd spectral laboratory. According to the results of emission spectral analysis, Prima Ltd product was acknowledge the best as regards chemical purity of the powder.
