Ceramics can be defined as inorganic, non-metallic materials that are typically produced using clays and other minerals from the earth or chemically processed powder. The broad categories or segments that make up the ceramic industry can be classified as follows: traditional ceramics, technical ceramics, and advanced ceramics.
Most people, when they hear the word ceramics, they think of art, dinnerware, pottery, tiles, brick and toilets. These ceramic products are commonly referred to as traditional ceramics. Some applications of traditional ceramics date back to about 8,000 BC.
The next category of ceramics, known as technical ceramics, have long become a ubiquitous feature in our lives for more than one hundred years. Many household appliances would not be able to function without ceramic insulators, such as electrical fuse and circuit breaker components, which are essential to a safe and reliable power supply. Technical ceramics are used in making spark plugs, which are essential components in automobiles and other internal combustion engines like lawn mowers, chain saw or weed eaters.
Advanced ceramics refer to materials, which exhibit superior mechanical and physical properties. These include superior corrosion/oxidation resistance, and thermal, electrical, optical or magnetic properties. Advanced ceramics generally include structural ceramics, electronic ceramics, ceramic coatings, and bio-ceramics.
The advanced ceramics era began approximately fifty years ago. These ceramics are made using chemically prepared powders so that the chemical purity and important physical properties can be controlled. Today, the market for advanced ceramics is large and growing as they continue to replace more traditional materials like metals and plastics in many applications while providing the only material solution in some specific and strategic applications. In many cases advanced ceramics are used with other materials to make up only part of an overall system.
Ceramics Vs. Steel
Our ceramic products outperform the hardest steel by 5 to 50 times with regards to longevity and are referred to as ceramic steel. The higher strength and higher hardness of our patented ceramic materials yield superior wear and abrasion resistance as well as superior corrosion resistance.
RocCera Tetragonal Zirconia (RTZ), also known as ceramic steel, is tougher than any other ceramic available today. Imagine ceramic parts with the toughness of steel, but with greater surface hardness, higher abrasion and corrosion resistance.
Zirconia Alumina Composites
Zirconia alumina is a mixture of zirconium oxide and aluminium oxide.
