XTL sintyron 99 al2o3 rectangular alumina ceramic corundum boat crucible

Rectangular alumina ceramic crucibles have several advantages and serve various purposes in

laboratory and industrial settings. 


1. High temperature resistance: Alumina ceramic crucibles can withstand extremely high temperatures,

making them suitable for applications requiring heating or melting of materials at elevated temperatures.

2. Chemical resistance: Alumina ceramic is highly resistant to chemical corrosion, making it an ideal

material for handling reactive substances or harsh chemicals.

3. Thermal shock resistance: Alumina ceramic crucibles have excellent thermal shock resistance, allowing

them to withstand sudden changes in temperature without cracking or breaking.

4. High purity: Alumina ceramic crucibles are made from high-purity alumina, ensuring that they do not

contaminate the samples or materials being processed.

5. Precise dimensions: Rectangular alumina ceramic crucibles are manufactured with precise dimensions,

ensuring a tight fit and optimal performance in various applications.

6. Longevity: Alumina ceramic crucibles are durable and long-lasting, providing reliable performance over

an extended period of time.


1. Melting and casting: Alumina ceramic crucibles are commonly used in metallurgy and foundry applications

for melting and casting metals, alloys, and other materials.

2. Thermal analysis: Alumina ceramic crucibles are used in thermal analysis techniques such as differential

scanning calorimetry (DSC) and thermogravimetric analysis (TGA) for studying the thermal properties of materials.

3. Chemical analysis: Alumina ceramic crucibles are used in chemical analysis techniques such as atomic

absorption spectroscopy (AAS) and inductively coupled plasma (ICP) for determining the elemental composition of


4. Sample preparation: Alumina ceramic crucibles are used for preparing samples in analytical chemistry,

environmental testing, and material science applications.

5. High-temperature reactions: Alumina ceramic crucibles are used for conducting high-temperature reactions,

such as sintering, calcination, and thermal decomposition.
