Ceramics
Ceramics are materials made from natural substances like clay. When clay is shaped and then heated to high temperatures in a special oven called a kiln, it hardens into ceramic. The high heat transforms the soft clay into a hard, often brittle material that can vary from porous to dense, depending on the type of clay and the temperature it’s fired at.
Ceramics are appreciated for their durability and heat resistance. That’s why they’re commonly used for pots, dishes, and tiles. Unlike metals, ceramics don’t rust or corrode, making them ideal for long-lasting uses. They can also withstand high temperatures without melting, which is why you’ll find ceramic items in both kitchens and scientific labs. Furthermore, ceramics can be decorated with various glazes and designs, leading to beautiful plates, mugs, and vases.
Over time, advancements in ceramic technology have given rise to special types of ceramics with unique properties. For example, certain ceramics are designed to be super hard and are used in items like armor. Others, such as those used in the heat shields of spacecraft, can withstand extreme temperatures, protecting the craft and its occupants during re-entry into the Earth’s atmosphere. From everyday dishes to advanced space applications, ceramics play a pivotal role in our world.
