1. Manufacturing Process
Meticulous techniques are involved when producing a 95% Alumina Tube, also known as an Aluminium Oxide Tube (Al2O3 Tube), with an outer diameter of 20 mm. First, high-purity alumina powder is blended with proprietary binders under controlled conditions to ensure uniform consistency. This homogeneous mixture is then shaped into cylindrical forms using methods such as extrusion or isostatic pressing, providing excellent dimensional stability. Subsequent drying stages eliminate moisture content to minimise potential defects during firing.
The next phase involves sintering the tubes at elevated temperatures to achieve optimal density and thermal properties. Throughout this stage, precise heat control is essential to prevent microcracking and maintain a smooth exterior surface. After cooling, the tubes undergo grinding or polishing procedures to achieve the exact dimensions and surface finish required for specialised applications. Each step is carefully monitored to guarantee that every finished 20 mm OD alumina tube meets stringent quality benchmarks.
