Latest Patents

Sung Yun Jo's latest innovations include two significant patents focused on pearlescent pigments with large aspect ratios. The first patent details a pearlescent pigment created by coating a metal or metal precursor on flaky alpha-alumina crystals, which are produced using an aluminum precursor aqueous solution and a zinc precursor aqueous solution. These unique crystals feature an average particle thickness of 0.5 µm or less and an average particle diameter of 15 µm or greater, boasting a large aspect ratio of 50 or higher. This enables the pigments to exhibit exceptional gloss, displaying a spectrum of metal and interference colors including silver, gold, red, purple, blue, and green.

The second patent highlights the preparation method for flaky alpha-alumina crystals with a large aspect ratio, comprising aluminum oxide, zinc oxide, and tin oxide. These crystals are derived from a mixed gel approach that involves hydrolysis of an aqueous aluminum precursor combined with zinc and tin precursor solutions. The resulting crystals possess an average particle thickness of 0.5 µm or less, an average particle diameter of 30 µm or more, and an impressive aspect ratio of 100 or greater. These attributes make them ideal for use as substrates for high-quality pearlescent pigments, abrasives, ceramic materials, and fillers.
