FAQs About Alumina Ceramic Crucibles/Boats

What is an alumina crucible?

An alumina crucible is a ceramic container made from aluminum oxide that is widely used in laboratory and materials research applications. It offers excellent thermal stability and chemical resistance, making it ideal for use in high-temperature experiments.

What factors should be considered when choosing an alumina crucible?

Several factors should be considered when choosing an alumina crucible, including temperature range, sample type and size, corrosion resistance, capacity and shape, and material purity. Each of these factors can impact the experimental outcomes and should be carefully considered to select the right crucible.

What are the different types of alumina crucibles available?

There are several types of alumina crucibles available, including straight wall crucibles, conical crucibles, cylindrical crucibles, rectangular crucibles, square crucibles, and custom-shaped crucibles. Each type has its own unique shape and properties that make it suitable for specific experimental requirements.

What temperature range can alumina crucibles withstand?

Alumina crucibles can withstand high temperatures, up to 1600°C or more, without cracking or degrading. The specific temperature range will depend on the type of crucible and the experimental requirements.

How does the sample type and size impact the choice of alumina crucible?

Different types of samples may require different crucible shapes or sizes, and the volume and viscosity of the sample will affect the choice of crucible. For example, experiments that require uniform heating may require a cylindrical crucible, while experiments that require a large surface area may require a rectangular or square crucible.

How can corrosion resistance impact the choice of alumina crucible?

Certain samples may require the use of a corrosion-resistant alumina crucible, and the choice of crucible will depend on the nature of the sample and the chemicals being used. High-purity alumina may be suitable for experiments that require a high level of corrosion resistance.
