Things You Must Know About the Ceramics

 

The word ceramics is originated from the Greek word keramos, which means ‘potter’s clay.’ Though, many composites that are classified as Ceramics today have no clay in it. Conventional ceramics include insulating materials, such as glass, abrasives, refractories, and enamels. They comprise of metal oxides, carbides, nitrides borides, and silicates—for instance, Tungsten carbide, Zirconia, Beryllia, Silicon carbide, Alumina, Magnesia. Modern Ceramics can be well-defined as the complexes of metals and non-metals. They usually have ionic atomic bonding between them. Depending on their atomic structure, ceramics are divided into Crystalline and Non-Crystalline ceramics. They are also distinguished into three material categories, Oxides, Non-oxides, and Composites. 

Properties of Ceramics

The following are a few of the properties of the Ceramics.

1. Ceramics have high hardness and a high melting point.

2. They are a good thermal insulator.

3. They are highly electricity-resistant.

4. They have a low mass density.

5. Generally, they are chemically inert.

6. Ceramics are brittle in nature.

7. They have low tensile strength.

8. They have zero ductility.

Benefits of Ceramics

Ceramics has unlimited benefits to serve.

1. The high melting point of Ceramics makes them an excellent refractory material.

2. Because of their high hardness, they can be used as abrasive powder and cutting tools.

3. Their high electric resistivity makes them apt to be used as an insulator.

4. Their low mass density results in lightweight machinery.

5. Their chemically inert nature makes them extremely robust.

Applications of Ceramics

1. Ceramic machining parts can be used in the space industry because of their low weight

2. They can also be used as cutting instruments.

3. They are also employed as refractory materials, thermal insulators, and electrical insulators.

Examples of Ceramics

The examples of the ceramics include barium titanite, boron oxide, boron nitride, ferrite, earthenware, magnesium diboride, porcelain, titanium carbide, zinc oxide, uranium oxide, zirconium oxide, Sialon (Silicon Aluminum Oxynitride), silicon carbide, silicon nitride, etc.

What is vitrification in ceramics?

  The process of vitrification can be defined as the formation of a substance into a  glass  that is mostly a non-crystalline amorphous solid. When we talk about the production of different ceramics, such as the Al2O3ceramic structure , the process of vitrification is responsible for its impermeability to water. The process of vitrification is usually done by heating materials until they are in a molten state, then cooling the liquid, often rapidly, so that it passes through the  glass  transition to create a vitrified solid. The chemical reactions and firm behavior of vitrified ceramics against the solvents like water are responsible for better integration in applications related to Al2O3 ceramics. There are different chemical reactions that often result in the formation of glasses. The vitrification of radioactive waste is one of the most common and important applications in order to get a stable compound that is appropriate for the disposal p...

Different Machining Methods of Ceramics

Ceramics have a unique combination of chemical, mechanical, and physical properties. It has high strength, low density, hardness, excellent stiffness, low electric and thermal conductivity, and brilliant corrosion resistance. The manufacturing techniques of ceramics (shape forming, sintering) permit to manufacture of parts of different shapes and sizes with great cost-efficiency. Here are described some of the methods of machining ceramics. Machining of Ceramics in the Pre sintered State Traditional machining techniques like milling, drilling, turning may be applied for the ceramic components in the pre-sintered state. Titanium nitride (TiN) coated high-speed steel instruments, Polycrystalline diamond tools, and tungsten carbide tools are used to machining pre-sintered ceramics. Grinding of Ceramics Grinding is the most popularly used technique of machining of Ceramics in the sintered state. The operation of grinding involves a revolving abrasive wheel eliminating the material from the...
