Application and Development Status of Industrial Ceramics

Introduction: Industrial ceramics are a class of fine ceramics that can perform mechanical, thermal, and chemical functions in applications.

Since industrial ceramics have a series of advantages of high temperature resistance, corrosion resistance, wear resistance, erosion resistance, etc., they can replace metal materials and organic polymer materials for harsh working environments, and have become a traditional industrial transformation, emerging industries and high-tech An important material that is indispensable, it has a very broad application prospect in the fields of energy, aerospace, machinery, automotive, electronics, and chemical engineering.

These industrial ceramics have various functions and applications, such as the use of high hardness, high wear resistance ceramics to produce mechanical parts, seals, cutting tools and other materials, using high wear-resistant, high-strength and high-toughness ceramics to produce Automotive wear-resistant, light-weight parts, heat-resistant and heat-insulating parts, gas turbine blades, piston crowns, inserts, etc., use of ceramics that are resistant to corrosion, contact with biological enzymes, chemical stability, and the production of smelted metal crucibles, heat exchange Appliances, biomaterials such as artificial articulated joints, etc., utilize unique ceramics that capture and absorb neutrons to produce various nuclear reactor structural materials.

With the continuous development of science and technology, further breakthroughs have been made in industrial ceramics, especially the development of multi-phase composite ceramics and nano-ceramics attracts attention. In the research of multiphase composite ceramics, advanced ceramics have been developed from the monophase and high-purity characteristics of Yawon to multiphase composites. Self-reinforced composite ceramic fibers or crystal-top reinforced composite ceramics, gradient-functional ceramics, and nanocomposite ceramics have been developed. It solves the technical problems of fragile single-phase advanced ceramics, low reliability, unsatisfactory room temperature strength, and insufficient toughness.

In the research of nano-ceramics, industrial ceramics are developing a number of nano-ceramic powders from the micro-scale to the nano-scale development of a new process, such as chemical precipitation, metal organic compound solution, chemical vapor reaction, etc., for advanced nano-ceramics. Production provides favorable conditions.

The application shows that the refinement of the nano-ceramic grains can obtain materials without defects or harmful defects, greatly improving the original performance of the ceramics, or even appearing new properties, making the ceramics more spacious. Therefore, nano-ceramics has become an emerging research course and has received much attention. It is expected that the future will be an era of high-performance advanced ceramics, which will surely play an increasingly important role in modern science and technology and modern industry.

There are many types of advanced ceramics, classified by raw materials, divided into the following major series:

1, oxide ceramics: mainly alumina ceramics, zirconia ceramics, mullite ceramics, etc.;

2. Telluride ceramics: mainly silicon germanium ceramics, antimony aluminum ceramics, silicon germanium boron ceramics, etc.;

3, carbide ceramics: mainly silicon carbide ceramics, titanium carbide ceramics, boron carbide ceramics, etc.;

4, boride ceramics: mainly titanium boride, boride zirconium ceramics.
