The difference between traditional ceramics and new ceramics

The main differences between traditional ceramics and new ceramics lie in their material composition, manufacturing processes, physical and chemical properties, and applications. In this article, we will explore the differences between these two types of ceramics and discuss their advantages, disadvantages, and applications.

1. Material composition

Traditional ceramics are usually made by mixing clay, quartz, feldspar, and other natural materials, and then firing them at high temperatures. New ceramic materials are usually made of high-purity inorganic compounds such as zirconia, silicon nitride, silicon carbide, etc. The chemical composition and crystal structure of these materials are more stable and uniform than traditional ceramics.

2. Manufacturing process

Traditional ceramic manufacturing typically involves processes such as mining, mixing, molding, drying, and firing. The manufacturing process is relatively simple, but it requires a large amount of labor and energy. The manufacturing of new ceramics usually adopts high-tech processes such as powder metallurgy and chemical vapor deposition. These processes can produce more complex and refined ceramic products, but require higher technological barriers and investment.

3. Physical and chemical properties

Due to their different material compositions and manufacturing processes, the physical and chemical properties of traditional ceramics and new ceramics are also very different. Traditional ceramics typically have low mechanical strength and fracture toughness, and are prone to breakage and damage. The new type of ceramic has higher hardness, strength, and toughness, and can withstand greater pressure and impact. In addition, the new ceramics also have excellent properties such as high temperature resistance, corrosion resistance, and oxidation resistance, making them more suitable for use in extreme environments.

4. Application

Traditional ceramics are usually used to make daily-use pottery, decorations, tiles, etc. Due to its simple craftsmanship, low cost, and easy portability, traditional ceramics play an important role in table culture, architectural decoration, folk art, and other aspects. The new type of ceramics is mainly used in industrial, medical, energy and other fields. Ceramics can be used to produce high-precision mechanical parts, artificial joints, medical dental implants, etc; Silicon nitride ceramics can be used to make high-temperature furnaces, pipeline valves, jet engine components, etc; Silicon carbide ceramics can be used to produce high-tech products such as electronic devices and solar panels. Due to its high performance, durability, and reliability, new ceramics have become an indispensable material in contemporary technological manufacturing.

In short, the difference between traditional ceramics and new ceramics is that traditional ceramics focus on aesthetics and practicality, and the manufacturing process is relatively simple; New ceramics, on the other hand, focus on material properties and technological innovation, with a wide range of applications and more technological fields. With the continuous advancement of technology and the expansion of applications, both traditional ceramics and new ceramics will play a greater role in future development.
