Industrial Applications of Glass and Ceramics


Ceramics and glass are mentioned here specifically because they are used in most of the industrial applications as they support manufacturing within fields such as metallurgical, mechanical, chemical, and energy production.

What Properties Makes Ceramics and Glass More Desirable?

Properties that make glass and ceramics desirable in these sectors are primarily its hardness, wear and corrosion resistance, resistance to chemical attack, thermal and electrical insulation, and compressive strength and high-temperature resistance.

The largest category of items is represented by refractories. Refractories are materials that are able to withstand the operating conditions of 1,000°C or greater. Although about 80% of the refractory market is described for by the metallurgical sector (for processing of both ferrous and non-ferrous metals), these items also have applications in other industries such as glass, ceramics, and cement manufacturing, and also in power generation.

Uses

Ceramics are also essential for filtration and separation procedures. Products containing membranes, macro filtration media, and filters, the difference among the three is that membranes have very minute pore sizes (below 10 microns); macro filtration media have pore sizes between 10 and 1,000 microns, and filters have large openings. Membranes are often manufactured from ceramic nanofibers. Ceramic separation media are less rampant and more expensive than polymeric media but are preferred for the treatment of high temperature and corrosive flows. They also render the benefit of being less affected by entangling and can be more conveniently regenerated with steam and heat treatments. The initial cost is usually compensated by its longer lifetime and minimal downtime.

Abrasive ceramics are used for grinding, polishing, and finishing operations and to make components with very constricted tolerances. They are traded as powders, beads, grains, and wheels.

The main application of glass is as panels and lenses for protective devices (e.g., machinery covers and eyeglasses), instrument composition, and manufacturing equipment, such as inspection systems.

Moreover, industrial ceramic products, include thermal barrier coatings and thermal insulating textiles, as well as electrical insulators for machinery sensors and components.

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...

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...

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...
