Ceramics have been a part of human history for thousands of years, shaping cultures and daily life. From ancient pottery to modern engineering marvels, ceramics are everywhere. But what exactly makes ceramics so special? Ceramics are non-metallic, inorganic materials that are typically crystalline in nature. They can withstand high temperatures, resist wear, and are often used in applications where metals and plastics fall short. Whether it's the mug you drink your coffee from, the tiles on your bathroom floor, or the heat shields on spacecraft, ceramics play a crucial role. Let's dive into 25 fascinating facts about these versatile materials and uncover why they remain indispensable in our world.
