What is Alumina Ceramic
The molecular weight of alumina is 102, and its chemical formula is Al2O3. This is a widely used material, and the main raw material of alumina ceramics is alumina. The melting point of alumina is 2100℃, which gives alumina ceramics excellent high-temperature stability! Therefore, alumina ceramics can be used in various high-temperature industries, and are often made into high-temperature furnace tubes, heating elements, thermocouple protection tubes, etc.
In addition to thermal stability, alumina also has excellent electrical insulation, which makes alumina ceramics widely used in some electrical equipment, the most common of which is ceramic substrates, insulators and other components in the semiconductor industry.
The hardness of alumina is comparable to that of diamond, and it is a very hard material, which gives alumina ceramics excellent wear resistance. Combined with chemical inertness, alumina ceramics can be used in harsh high-intensity environments as well as in easily corrosive environments, and are excellent materials!

What is the difference between alumina toughened zirconia (ATZ) and zirconia toughened alumina (ZTA)?
Zirconia toughened alumina (ZTA) and alumina toughened zirconia (ATZ) are both advanced composite ceramic materials. They differ mainly in the composition of the base ceramic phase and the reinforcement phase. The basic ceramic phase of ZTA is alumina (Al2O3), and its reinforcing phase is zirconia (ZrO2) particles, which have better thermal shock resistance and wear resistance. On the other hand, ATZ has higher corrosion resistance and chemical stability, and alumina-toughened zirconia has better toughness and higher cost.
Should I choose alumina or another material?
Compared with other ceramic materials, alumina ceramics have higher hardness and better wear resistance. They are common in daily life, have reasonable mining costs, are widely used, and have a high cost performance. If you want to use high-performance and low-cost materials, then alumina is very suitable!
