The use of graphite in Sri Lanka has a long history, that dates back to 1675. Sri Lankan graphite has gained popularity all over the world for its high purity and offers many processing applications in graphite lubricants, flake graphite, carbon brushes, refractory bricks and midget electrodes and nano-technology.
Three main types of clay - kaolinite, ball clay and brick clay - are used for export industries. Yellow, red and blue colour ball clay is found in Sri Lanka’s hill country. These are used to make casts and as refractory material because of their attributes of strength and high plasticity. Brick clay is found in most of the river valleys and is commonly used in the production of bricks and tiles.
