Technological Advances in High Purity Alumina Ceramics
The development and production of Al2O3 porcelain originated in Germany. Since then, major American companies have successively developed various Al2O3 ceramics. In the field of research, they consider ceramic and metallization technologies together, so that the two can be better matched and adapted.
Facts have proved that among the many varieties of Al2O3 ceramics, high Al2O3 ceramics are the best. Its preparation process is simple, the basic performance is excellent, the cost is low, the sealing process is suitable, and the practical value is excellent.
It should be pointed out that in the early days, when the Al2O3 content was greater than 75% or 80% and 85%, it was called high Al2O3 ceramics. However, with the technical progress and a large number of applications of Al2O3 ceramics and the continuous improvement of its performance at home and abroad, the author believes that it is more appropriate to call high Al2O3 ceramics with 95%±1% (mass ratio) Al2O3 ceramics. rigorous.
At present, high Al2O3 ceramics have been widely used in various industrial fields such as electronics, metallurgy, automobiles, petroleum, chemical industry, machinery, aviation, aerospace and biology. Among the big family of Al2O3 ceramics, it can be called the largest output, the most varieties, and the most applications. wide. It needs our industry insiders to conduct in-depth research to further improve its performance and reliability.
