Alumina Crucible, Al2O3 Crucible Conical, 99%, 10 mL FAQs

Q1: What are the key material properties of Alumina Crucible, Al2O3 Crucible Conical, 99%, 10 mL?

A1: This 99% pure alumina conical crucible provides high density, thermal stability up to approximately 1 700°C, and excellent mechanical strength. Its low thermal expansion coefficient reduces the risk of cracks when subjected to abrupt temperature changes. The material is resistant to chemical corrosion, enabling it to withstand acidic and alkaline environments. Its hardness ensures minimal wear, maintaining the crucible's dimensions and structural integrity.

Q2: How can this ceramic product be processed or fabricated?

A2: These crucibles are typically formed through techniques such as slip casting, isostatic pressing, or die pressing, followed by high-temperature sintering. During fabrication, fine alumina powders are controlled for particle size and purity to ensure uniform density. Advanced firing profiles, featuring precise temperature ramp rates, are often employed. This process promotes full densification, giving the final product consistent dimensions, reduced porosity, and excellent mechanical properties while maintaining the desired conical shape.

Q3: Which quality standards and certifications apply to Alumina Crucible, Al2O3 Crucible Conical, 99%, 10 mL?

A3: These crucibles typically conform to stringent global standards, including ASTM C799 for refractory performance and ISO 9001 for manufacturing quality assurance. Many suppliers also certify compliance with RoHS regulations, ensuring they are free of restricted substances. Strict inspection protocols, such as dimensional accuracy checks and statistical process control, help guarantee consistent quality. Regular third-party audits further affirm product reliability and purity.

1. Material Properties and Advantages

Manufactured from 99% pure Al2O3, the 10 mL capacity conical alumina crucible provides excellent dimensional stability and high-temperature performance. Its dense microstructure minimizes grain growth and ensures that the crucible retains structural integrity even under severe heating cycles. This composition is beneficial in processes requiring chemically inert containers, as the ceramic resists most acids and alkalis. The conical shape helps distribute thermal stress more evenly, reducing the risk of cracks or fractures under abrupt temperature changes.

Durability and reliability are also key advantages of this crucible’s design. The smooth internal surface facilitates easy cleaning and maintenance, ensuring minimal cross-contamination during flavour, colour, or chemical transitions. Additionally, the crucible’s excellent dielectric properties make it suitable for applications in electronic device fabrication and high-frequency processes. Due to its robust nature, this alumina crucible helps maintain consistent results across various laboratory and industrial procedures.

2. Comparative Analysis with Alternative Materials

In comparison to metals such as platinum or nickel-based alloys, 99% alumina does not introduce risks related to oxidation or corrosion in high-temperature environments. Metallic containers may react with certain chemicals during extreme heating, potentially contaminating sensitive materials. Conversely, the inert properties of alumina enable the 10 mL conical crucible to manage a wider range of laboratory reagents without compromising purity or structural integrity.

Accompanied by its cost-effectiveness, alumina represents a better long-term investment than single-use or disposable alternatives such as graphite crucibles. Graphite is prone to oxidation at elevated temperatures and is generally unsuitable for applications requiring minimal contamination. Alumina’s strength, thermal conductivity, and resistance to chemical attack establish it as a preferred choice for researchers, metallurgists, and other professionals in advanced industries seeking reliability in high-temperature processes.
