At the intersection of technology and industry, a seemingly ordinary material is quietly changing our lives - that is, ceramics. You've probably picked it up in the kitchen or admired it in a museum, but did you know that ceramics aren't just an everyday object, they're an integral part of modern technology?
What are Technical Ceramics?
First, let's define technical ceramics. Technical ceramics, also known as engineering ceramics or advanced ceramics, are inorganic solid materials with excellent mechanical, electrical and/or thermal properties. They are extremely pure and are typically made from metal compounds such as oxides, carbides, or nitrides. These properties enable ceramics to extend product life, increase efficiency, reduce overall maintenance costs, and improve product performance.
The magic of technical ceramics.
The magic of technical ceramics lies in their unique properties. First of all, they are extremely hard, more than four times harder than stainless steel. This high hardness results in excellent wear resistance, which enables many technical ceramics to maintain their precise, high-tolerance finish for long periods of time.
Secondly, technical ceramics have the ultimate compressive strength and can withstand loads of up to 1000 to 4000 MPa. Titanium, on the other hand, is considered a very strong metal with a compressive strength of only 1000 MPa.
In addition, technical ceramics have a low density, being lighter than stainless steel and titanium, and only the softer aluminum has a similar density. This high hardness and low weight make technical ceramics widely used in various industries, and their properties and performance are not comparable to other materials.
Technical ceramics can also withstand high temperatures, maintaining their mechanical and electrical properties. In contrast, all metals and polymers can compromise their properties at high temperatures, while technical ceramics continue to function with consistent performance and reliability. This property makes it ideal for high-temperature applications such as furnaces, jet engines, braking systems, and cutting tools.
Technical ceramics are also excellent electrical insulators with high dielectric strength, making them particularly suitable for electrical applications at high temperatures. In addition, the ability to combine insulators with structural components opens up the possibility for many product innovations.
However, there are also some drawbacks to technical ceramics. For example, their shear forces have poor tensile strength, which makes them potentially inferior to metals in applications that need to withstand shock or vibration. In addition, technical ceramics are brittle and easy to break. However, with the development of technology, we believe that these problems will be solved.
Overall, ceramics are a material that is changing the world. Its high performance and diversity make it play an important role in various fields, Junjie Ceramics has been studying in the field of industrial ceramics processing for many years, and constantly improving processing technology and processes. In the future, Junjie ceramics has reason to believe that ceramics will bring us more surprises.
