High Alumina Crucible

High Alumina Crucible

1. High Alumina Crucible have strong corrosion resistance to most acids, bases, and salts, especially stable in weakly alkaline environments such as anhydrous sodium carbonate melting. Its chemical corrosion resistance comes from the inertness of the material itself and the uniformity of its microstructure, which can effectively avoid reactions between experimental reagents and containers, ensuring the purity of the sample and the reliability of experimental data.

2. By optimizing the sintering process, the bending strength of the High Alumina Crucible can reach over 350MPa, the compressive strength exceeds 1200MPa, and the coefficient of thermal expansion is low, which can withstand mechanical vibration and temperature gradient changes in experiments.

3. The thermal conductivity of High Alumina Crucible is significantly better than traditional ceramic materials, which can quickly and uniformly transfer heat, reduce the temperature difference between the sample and the crucible, and improve experimental efficiency and result accuracy.

4. Although the initial cost of High Alumina Crucible is higher than that of ordinary ceramic crucibles, their long service life and repeatable cleaning greatly reduce long-term experimental costs.

1. High Alumina Crucible sed for melting high melting point metals and alloys such as titanium and zirconium, avoiding reactions between crucibles and molten metals, ensuring precise control of alloy composition.

2. High Alumina Crucible in hydrothermal synthesis, sol gel method or high-temperature calcination, keep the purity of the reaction environment and avoid the introduction of impurities affecting the performance of nanoparticles.

3. High Alumina Crucible used for preparing piezoelectric ceramics, transparent ceramics, etc., its high thermal conductivity accelerates the sintering process, and its dense structure reduces impurity penetration.

4. When using high-temperature melting method to decompose insoluble samples such as silicates and ores, High Alumina Crucible can withstand the strong alkaline environment of mixed fluxes.

5. During the ashing process of food and environmental samples, the low background value of High Alumina Crucible can reduce errors in trace element analysis.

• Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.

• Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.

• Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
