| dc.description.abstract | China clay is widely used in many industries such as ceramics, paper, paints, plastics and rubber. As most of these industries require clay having high brightness, a number of techniques have been developed to achieve that. This paper briefly reviews the methods used in other countries and discusses the possibility of developing an electrolytic method to brighten Sri Lankan china clay. An instrument to measure brightness of powders has been designed and fabricated in this department. The principle involved is the measurement of reflected light from specimens at an angle 45° electronically. | en_US |
