High Purity 99 Dense Alumina Channel Blocks from China Factory - Top Suppliers for Industrial Applications
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
99 dense alumina channel blocks are no glass pollution, eliminate glass impurity, bubble, ‘Cat-Scratch’ and reducing defects of glass production. The production yield-rate can be highly improved, especially for crystal glass, cosmetic glass, perfume glass, high-grade container glass etc.
-
High Density: Dense alumina has a high density, contributing to its mechanical strength and durability.
-
Thermal Stability: It can withstand high temperatures, making it suitable for high-temperature applications.
-
Wear Resistance: Alumina is highly resistant to wear and abrasion, which is beneficial in harsh environments.
