In today’s class, we will be talking about ceramics and glasses. Enjoy the class!

Ceramics and Glasses

Ceramics and glasses are inorganic, non-metallic materials consisting of metallic and non-metallic elements bonded primarily with ionic and covalent bonds.

Ceramics are inorganic, non-metallic compounds including most minerals and rocks which cover almost the whole of our planet. They can be divided into two categories of traditional and advanced ceramics.

The word “Glass” comes from an Indo-European root which means “shiny” and also has given us the words glare, glow and glaze. The Latin equivalent phrase for glass is vitreous.

Types of ceramic

  • Stoneware:

Is an umbrella term for ceramics fired at a higher temperature? It is known for being impermeable and hard so it’s not easily scratched.

  • Clay products:

In this category, many of the common ceramics like bricks and tiles are used. They are basically prepared from clay. For their shape and state, they are processed and pressed in a wet plastic state after which they are dried and then fried.

  • Refractories:

Ceramic can resist higher temperatures and that is why they are also used as refractories. Refractory ceramics can withstand very high temperature and are thus used as insulating materials. They can also resist high stress.

Uses

  • Pottery:

Used to make decorative and household products, symmetric objects like plates, cup and saucer, flowerpot, pot, vessels.

  • Whitewares:

It is used to produce crucibles, Spark-plug, dishes, Electrical insulators like high voltage insulators and low voltage insulators and high-class potteries

  • Stone wares:

Stone wares are mainly used to construct sewage pipes, public lavatories, underground cable sheathings, drainage pipes, valves and pumps in chemical industries

  • Tiles:

As we know ceramic tiles are used for construction works. It is used to cover the surface of the floor, wall, and ceilings. Nowadays tiles are also used for decorative purposes as it is utilized for the interior and exterior finishing works.

Properties
  1. High melting points (so they’re heat resistant).
  2. Great hardness and strength.
  3. Considerable durability (they’re long-lasting and hard-wearing).
  4. Low electrical and thermal conductivity (they’re good insulators).
  5. Chemical inertness (they’re nonreactive with other chemicals).

Types of glass

  • Tempered Glass for side windows:

Tempered glass is a type of glass that breaks into small blunt pieces instead of sharp dangerous shards upon collision. Thus, it is used in the side windows and rear windshield of automobiles and does not harm the passengers in the event of an accident.

  • Laminated Windshields:

Laminated glass is a type of glass which consists of two sheets of glass with a plastic inter-layer separating them. Thus, laminated glass is quite impact-resistant, and in the event of breakage its glass pieces remain stuck to the plastic interlayer, thus protecting the passengers from injury. Clear Glass

  • Tinted Glass:

Tinted glass is annealed glass that has a coating or a film that imparts it colour and reduces its light transmission. AIS Tinted Glass is a body tinted glass which absorbs energy from solar radiation.

  • Frosted Glass:

Frosted glass is a translucent glass made by the process of sandblasting or acid etching. Its pitted, rough surface gives it a foggy appearance, thus making it the perfect solution for privacy. AIS Krystal, India’s only branded Frosted Glass, obscures the view while allowing light to pass through it.

Properties
  1. It absorbs, refracts or transmits light. It can be made transparent or translucent.
  2. It can take excellent polish.
  3. It is an excellent electrical insulator.
  4. It is strong and brittle.
  5. It can be blown, drawn or pressed.
  6. It is not affected by the atmosphere.
  7. It has excellent resistance to chemicals.
  8. It is available in various beautiful colours.
