High-Density Sintered Alumina Channel Blocks - Premium Quality from China Suppliers & Factory
Manufacturing Process
-
1Raw Material Preparation
High-purity alumina powder and various particle grains size are prepared.
-
2Forming
The raw material is formed into the desired shape using techniques such as casting or extrusion.
-
3Sintering
The formed blocks are sintered at high temperatures to achieve the required density and mechanical properties.
The Advantages
Dense alumina has a high density, contributing to its mechanical strength and durability.
It can withstand high temperatures, making it suitable for high-temperature applications.
Alumina is highly resistant to wear and abrasion, which is beneficial in harsh environments.
It resists chemical attacks from acids and alkalis, enhancing its longevity in corrosive settings.
Alumina is an excellent electrical insulator, making it useful in electrical and electronic applications.
Application
This product is mainly used in the hot end of furnaces such as tableware glass and bottle glass, container glass furnace etc.
