Uses Of Ceramics- CeramicNinja.com

Ceramics are everywhere! In our day to day life definitely, we use ceramics. When thinking of ceramics most of the people say that ceramics are just used for making pottery, it is not a fact! Let us see in this article where the ceramics are really used for!

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

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

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

As we know ceramic tiles are used for construction works. It is used to cover the surface of floor, wall, and ceilings. Nowadays tiles are also used for decorative purposes as it is utilized for the interior and exterior finishing works.
Based on the need both the glazed and unglazed tiles used.
Porcelain tiles are durable and highly resistant to water (water absorption is nearly 0.5%). So these types of tiles are preferred in indoor bathrooms and kitchens
Quarry tiles are very hard and they don’t break easily, so they are fit for outdoor uses.
Terracotta tiles are unglazed tiles which are hard and unglazed, thus they are used in both indoor and outdoor applications

Porcelain is used to manufacture
 Crucibles
 Electrical insulators
 Porcelain Tiles
 Used in tunnels and subway
 Porcelain enamel is used to coat water heater sinks, bathtubs, stoves, grills
 Food and agricultural industries

Used to produce plates, glasses, bowls, mugs, utensils, dinnerware,

Abrasives are mainly used for polishing, grinding, surface finishing and cutting operations.

Raw material uses:

Silica

• Since the toughness is lower, it is used in the lightweight finishing applications.
• Bigger grit gives rough finish hence used for surface grinding
• Smaller grits posses smooth finish and used for fine finishing applications.

Emery

• Emery is also known as black sand
• It is a blocky grain, thus used in polishing operations

Garnet

• Used in wood products finishing applications
Crocus
• Used for wood finishing, metal finishing and flat glass surface finishing applications

Diamond

• It is the hardest material.
• Used as a diamond cutting wheels for glass and stone cutting, ceramic tool cutting, cemented carbide tool cutting.

Silicon carbide

• Used for grinding and polishing applications.
Alumina
• Used for cutting operations, cold cutting
• Used for grinding operations
