Alumina Crucibles

Product Description

Alumina Crucibles – High-Purity Ceramic Crucibles for High-Temperature Applications

Alumina crucibles are essential ceramic containers designed for high-temperature applications, chemical resistance, and long-term durability. Made from high-purity aluminium oxide (Al₂O₃), they offer excellent thermal stability and are widely used in research, metallurgy, materials testing, and industrial labs.

At M-Kube, we supply premium-quality alumina crucibles in Australia to meet a wide range of scientific and manufacturing needs. Whether for melting, calcination, or sample preparation, our crucibles ensure purity, precision, and performance in every batch.

Standard and Custom Alumina Crucibles for Laboratory and Industrial Use

M-Kube offers a broad selection of standard alumina crucibles in various shapes such as cylindrical, conical, rectangular, and boats. Beyond our stocked range, we also provide custom ceramic crucible solutions tailored to your exact process requirements.

Our customisation capabilities include:

• Modified geometries and wall thicknesses
• Open- or closed-top designs, with or without lids
• Polishing, engraving, or labelling options
• Support for both small-scale R&D and large-volume production
• Crucibles with precision tolerances upto about +/-0.05mm can be offered, depending on the sizes

With responsive local service and expert support, we help you source or design the right technical ceramic crucibles — every time.

Over the years, these sizes and shapes have been among our go-to standard offerings — tried, tested, and trusted by many

Frequently Asked Questions:

What is the purity of standard alumina crucibles?

Most high-performance crucibles are made from:

• ≥99% alumina for lab use
• 95–99.7% or 99.8% alumina for industrial applications

Are conical crucibles available in different capacities?

Yes, they typically range from 5 mL to 500 mL, but custom sizes are available.

Can alumina crucibles be reused?

Yes—if not damaged or contaminated, alumina crucibles can be reused multiple times. Avoid rapid thermal cycling to reduce cracking.

Can alumina crucibles be used in vacuum or inert gas furnaces?

Yes. They are ideal for vacuum furnaces, argon, nitrogen, or reducing atmospheres.

What should I check when selecting a supplier in Australia?

• Material purity certification (≥99%)
• Accurate dimensions and volume
• Suitability for high temperatures (≥1600–1700°C)
• Delivery lead time and local stock availability
• Technical support and datasheet availability

What types of alumina crucibles are commonly available in Australia?

• Cylindrical (most popular)
• Boat
• Conical
• Lidded or open-top
• Rectangular/ Tray
• Partition crucible
• Custom designs based on customer drawings
• With or without lid

High-purity (99–99.7%) alumina grades.
