Title: Kwang Choong Kang: Innovator in Pearlescent Pigments

Introduction

Kwang Choong Kang is an accomplished inventor based in Cheongju-si, South Korea. With a notable portfolio of three patents, he has made significant contributions to the field of materials science, particularly in developing advanced pearlescent pigments and alpha-alumina crystals.

Latest Patents

Kang's recent patents focus on innovative formulations and methods for producing pearlescent pigments with large aspect ratios. One of his notable inventions is a pearlescent pigment that features a large aspect ratio and outlines a method for its preparation. This invention aims to enhance the visual appeal of pigments by coating metals or metal precursors onto flaky alpha-alumina crystals. Notably, these crystals are characterized by an average particle thickness of 0.5 micrometers or less, an average particle diameter of 15 micrometers or more, and an outstanding aspect ratio of 50 or higher, resulting in superior gloss and a spectrum of vibrant metal and interference colors, including silver, gold, red, purple, blue, and green.

Another of Kang's significant contributions is the patent on flaky alpha-alumina crystals with large aspect ratios. This innovation details a preparation method that involves hydrolysis of mixed gel solutions containing aluminum, zinc, and tin precursors, followed by aging, drying, and crystallization processes. The resulting crystals possess an average thickness of 0.5 micrometers or less and an average diameter of 30 micrometers or more, achieving an aspect ratio of 100 or higher. These characteristics make the crystals suitable for use as high-quality pearlescent pigment substrates, abrasives, ceramic materials, and filling materials.
