Ceramics in the real world

Ever thought about the plethora of materials that we come interact with on a daily basis? There are an infiinit amount of materials with unique charactoristics that are used to create all sorts of items we use everyday.

Today, allow me to tell you aboutĀ ceramics in the real world.

Often when people think about ceramics, they merely think of pottery and decorative items. However ceramics play an extremely important role in for many object you see and many you don’t.

Aside from the day-to-day items of glass wares and ceramic tiles, the ceramics in the present day are vital in aiding the operation of computer systems and electronic products, in medical devices for improving people’s health in a variety of ways, in providing global telecoms, and in safeguarding members of the military.

Ceramics are generally defined as inorganic, non-metallic materials that are made from powdered chemicals. They are typically crystalline in nature (their atoms are arranged in a systematic manner) and are compounds formed between metallic and non-metallic elements such as aluminum and oxygen (alumina, Al2O3), calcium and oxygen (calcia, CaO), silicon and nitrogen (silicon nitride, Si3N4), and so on.

Various “advanced ceramic” products are manufactured by combining high-purity chemicals into desired shapes and then heating them to very high temperatures. The shaped ceramic products thus made can have many desirable properties such as heat resistance, hardness, strength, low electrical conductivity, and unique electro-mechanical characteristics. Thus advanced ceramics are ceramics which are made by tightly controlled methods and therefore they exemplify an “advancement” over the general definition. As a consequence of these refined methods, a new class of ceramics called “advanced ceramics” is born.

Long lasting and harder than steel, advanced ceramics may be found in aircraft engines, automotive engines, cutting tools used for making metal products, the skin of space shuttles, knives, bullet proof armor, artificial hip-joints, computers and microelectronics.
