Advantage of Ceramics over other materials
As ceramics are heat resistant, they can be used for many tasks for which materials like metal and polymers are unsuitable.
There are many advantageous properties of Ceramics such as high hardness, high durability, high thermal and electrical resistance, corrosion resistance, less dense or lightweight and high temperature resistance. One of the main reasons why ceramics is economical and advantageous is that its raw materials are inexpensive and abundant in nature.
Ceramic materials are part of our daily lives. Traditional ceramic products like ceramic figurines, decorative earthenware, kitchen wares, toilet bowls, floor tiles, wall tiles etc. have been widely used all over the globe and is present in almost every household. Silicate bottles and glasses, cements, devices and T.V. components such as resistors, capacitors etc. are common products which have been part of our lives. These are the ceramic products that we did not know are made out of ceramic raw materials.
Categorization of Ceramics
It can be categorized into two main courses:
It comprises of pottery, porcelain making, brick & tile manufacturing, cements processing and glass products which are silicate based.
Advance ceramics on the other hand include application of lightweight ceramics in modern military armors such as Silicon Carbide and Boron Carbide, nitrides, non-silicate glasses and several other materials.
Some of the Applications of Ceramic Products:
Ceramic Electrical Insulators are used in Power Line Insulation
Floor Tiles and Wall Tiles are made of Ceramic
Ceramic Power Line Insulators
Insulators are used to isolate conductors from other components to prevent forthcoming and unnecessary damages on devices. Plastic, rubber and leather are the most commonly known insulating materials. These materials are effective insulating materials as they are non-conductive. However, insulators could become conductors when excessive amount of large voltage are applied in it – which is known as the breakdown voltage of insulator. Thus engineers continually developed materials which could durably withstand high voltage in a long run. One of the best insulating materials which are being used today especially in overhead power line are ceramic materials.
There are mainly two types of overhead power line insulators;
pin type insulators which basically support conductors above structures and the
suspension type of insulators which support hanging conductors in structures.
Materials used as insulators in high-voltage power transmission need to have high dielectric strength such as glass, porcelain and composite polymer materials. Although glass has higher dielectric strength than porcelain, the cold surface of glasses collects dews especially when humid air is in contact with it.
(4, 7, 8) Pin Type Insulators; (5, 6, 9) Suspension Type Insulators
Generally, insulators have two main functions; to isolate conductors and to separate conductors from other conductors. Most ceramic materials possessed high dielectric strength. So generally, ceramic materials have very low electrical conductivity due to its ionic-covalent bonding, which makes it good electrical insulators. Additionally, ceramic materials have low thermal conductivity which also supports its insulating capability as electrical conductivity is also influenced by temperature. This is because the movements of the electric charge or charge excitation are primarily caused by thermal energy.
Ceramic Floor Tiles & Wall Tiles
Floor tiles and wall tiles are used as interior and exterior designs in our households, on industrial buildings and other public structures. Ceramic tiles have been the most common and the most popular design that we can notice on every household or buildings.
Most of the ceramic industries primarily manufactured floor and wall tiles because they’re economical yet profitable and aren’t complicated to make. The raw materials used in making these ceramic products are abundantly available in nature. Raw materials such as clay, feldspar and silica are the main component in making ceramic tiles.
Applications of Ceramics in our modern life
Our roofs, bathrooms and kitchens are covered in ceramic tiles. Ceramic can be glazed with different colours and printed with any design, so tiles can be tailored to different people’s tastes. They are tough and easy to wipe clean once glazed which is perfect for use in the kitchen or bathroom!
Majority of crockery and pots are made from ceramic. From unglazed to glazed, mortar and pestles to the mug that holds your tea, ceramic is a staple material in the kitchen. Ceramic knives have also become common, they are one of the hardest knives you can buy yet are extremely lightweight!
Our homes are made from brick and are held together by cement, both of which are types of ceramic. Without ceramic, what would we use instead to create the four walls of our homes?
Sanitary ware such as toilets, sinks and bath tubs are made from ceramic. Ceramic can be glazed and fired so that it becomes non-porous, perfect for sanitary ware which gets used every day and is, of course, in contact with lots of water!
NASA’s Space Shuttle had thousands of heat-resistant tiles protecting its exterior from overheating due to friction generated by Earth’s atmosphere. Future reusable space planes are expected to use a new, slimline ceramic material that will enable it to be both more aerodynamic and withstand temperatures up to 2400°C. Composite ceramics are also used to create the nose cones of spacecraft!
Ceramic can help to decrease pollution and capture toxic materials. Today’s catalytic converters are made with ceramic and help convert harmful fumes into non-toxic gases, therefore having a huge benefit on the environment. Ceramic components can be found in almost every aspect of a vehicle and are a major contributor to advances in hybrid and eco-friendly vehicles.
7. Artificial Bones and Teeth
Toughened ceramic is used in hip replacements and is designed to be porous so that it can stimulate natural bone growth around the artificial joint. You will also find ceramic fillings for your teeth where the ceramic is chemically bonded to your tooth making it extremely strong.
8. Electronic Devices
Televisions contain ceramic insulators, computers have silicon chips and the electric motors in your vacuum cleaner or blender are also made using ceramic!
