Non-metallic materials are substances composed of non-metal elements or compounds. Since the 19th century, with the rapid development of industry and science and technology, especially in the fields of inorganic and organic chemistry, humans have begun to create and synthesize a wide range of new non-metallic materials from natural resources such as minerals, plants, and petroleum. Examples include cement, artificial graphite, advanced ceramics, synthetic rubber, plastics (synthetic resins), and synthetic fibers. These materials have become essential in modern industries due to their unique properties, such as high strength, corrosion resistance, and thermal stability, which often surpass those of traditional natural non-metallic materials and even some metals. Their applications continue to grow rapidly, playing a vital role in construction, electronics, automotive, and many other sectors.
