Ceramics Usage in Modern Technology

While you are at home today, have a look around and see how many electronic devices that would be unusable if it weren’t for the help of ceramics. In fact, a lot of what you see is ceramic based. It may not be apparent to the naked human eye, but ceramics plays an important role almost everywhere you look.  Next time you are looking out the windows of your house or out windows of your car that you drive, there are ceramic materials.

Don’t forget bricks, telephone and power insulators, tiles, crockery and toilet bowls. Every item listed requires the skills of a ceramic engineer to design and manufacture the materials that are required to perform their jobs. Another interesting fact is the bio-ceramics used on hip replacements and space shuttle tiles. Even during the war ceramics protected soldier. Being designed at the moment are ceramic engines that will be better for the environment and more fuel-efficient. So you can see how ceramics is being used in Modern Technology.

Functional ceramic materials that play roles in telecommunications and ultrasound imagery are piezoelectric materials. Piezoelectric are material substances that have the ability to be turned into mechanical signals (such as sound waves) into electrical signals, and vice versa. These qualities make them useful in the production of microphones, gramophone pickups, earphones, and also to create a spark for lighting gas flame.  These materials can be a number of items such as, crystals, some ceramics biological matter such as bones, proteins and DNA.

Ceramic Engineering is using science and todays technology to create gadgets from non-organic and non-metal materials. The process of ceramic engineering is either the process of heat or by using lower temperature to produce reactions from pure chemicals. The ceramic process follows this sequence.

  • Milling– this is the process of making larger sized materials into smaller sized material. Machinery usually performs milling.
  • Batching– this part of the process is sorting the oxides to recipes, in preparation for mixing and drying.
  • Mixing– this is a part of the process that is also done by machine, and is mixing the materials together.
  • Forming– this is the part of creating shapes from the   mixed materials.  Shapes like toilet bowls and even spark plugs are created.
  • Drying– this is the removal of the water and binder.  Tunnel dryers can be used or also can be dried by spray dryers.
  • Firing– this is the final part of the process when the dry pieces pass through a controlled heating process.  This is a process called sintering or bonding and is the chemical changes in Oxides.

From the moment you wake up to the moment you go to sleep your day is filled with applications that require ceramics. It is intertwined in to our lives way more than most people have the knowledge of.
