M-Kube - Alumina Crucibles
M-Kube Enterprise supplies high-purity alumina crucibles made from premium aluminum oxide (Al2O3), delivering unmatched thermal performance and chemical resistance. Designed for high-temperature applications, these ceramic crucibles are essential in materials testing, analytical labs, metallurgy, and research environments throughout the United States. Whether you’re melting metals, conducting calcination, or preparing samples, our alumina ceramic crucibles offer the purity, durability, and precision your process demands.
Standard and Custom Alumina Crucibles for Lab and Industrial Use
We offer a wide range of standard alumina crucibles—including cylindrical, conical, rectangular, and boat-shaped variants—along with custom crucible solutions tailored to your specifications.
Our customization application capabilities include:
- Custom shapes and wall thicknesses
- Open- or closed-top options, with or without lids
- Polishing, labeling, and engraving
- Support for small-batch R&D and large-volume manufacturing
- Precision tolerances up to ±0.05mm
At M-Kube Enterprise, we work closely with clients in the USA to ensure reliable sourcing and custom engineering for their ceramic requirements. Some of the standard dimensions are
Our high-performance ceramic crucibles are designed to withstand the most demanding conditions:
- Heat resistance up to 1700°C
- Inert to acids, alkalis, and molten materials
- Excellent thermal shock resistance
- High mechanical strength and dimensional stability
- Non-contaminating and corrosion-resistant
- Ideal for high-purity analytical and thermal applications
These properties make our high-temperature crucibles a reliable choice for laboratories and industrial settings alike.
Our alumina crucibles are used across a variety of American industries, including:
- Analytical labs for ashing, melting, and calcination
- Thermal analysis such as TGA and DTA
- Sample prep in mining, metallurgy, and materials science
- Ceramic and metal powder processing
