Alumina Crucible, Al2O3 Crucible Conical, 95%, 1000 mL FAQs

Q1: What are the key material properties of Alumina Crucible, Al2O3 Crucible Conical, 95%, 1000 mL?

A1: Alumina (Al2O3) at 95% purity provides exceptional mechanical strength, chemical inertness, high thermal conductivity, and resistance to thermal shock. With a maximum working temperature often exceeding 1 600°C, this material exhibits excellent corrosion resistance against most acids and alkalis. Its strong dielectric strength makes it suitable for electrical insulation applications, while its low expansion coefficient ensures dimensional stability under temperature fluctuations.

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

A2: Alumina crucibles are commonly formed through powder compaction or slip casting, followed by high-temperature sintering in controlled atmospheres. The starting powder is carefully milled and blended to ensure uniform particle size distribution, which helps achieve consistent density and minimal porosity. After shaping, the crucibles undergo gradual heating to remove binders and facilitate densification. Post-sintering, precision machining may be employed to achieve desired dimensional tolerances or surface finishes.

Q3: Which quality standards and certifications apply to Alumina Crucible, Al2O3 Crucible Conical, 95%, 1000 mL?

A3: Alumina crucibles of this type typically adhere to both ISO 9001:2015 and ISO 14001:2015 standards, ensuring stringent quality management and environmental responsibility. They also often meet ASTM C786 or equivalent material-specific specifications to verify purity, dimensional accuracy, and thermal performance. Ongoing quality checks, including visual inspections, density measurements, and mechanical strength testing, confirm compliance with customer requirements. Manufacturer certifications and material data sheets further validate traceability and reliability.

1. Manufacturing Process

Through precision forming methods, the 95% alumina powder is first moulded into a conical shape corresponding to the 1000 mL volume capacity of the crucible. This preliminary structure is then subjected to high-temperature kiln firing, which initiates the sintering process and ensures the material’s crystalline development.

Because alumina requires precise temperature control to maintain its chemical integrity, each crucible is fired in stages to remove residual moisture and binders. Following a controlled cooling period, the crucibles are inspected for dimensional accuracy before moving on to final finishing operations that ensure their surfaces remain smooth and free from microcracks.

2. Quality Control Measures

Meticulous testing procedures are employed to confirm the crucible’s structural integrity, particularly its ability to withstand thermal shock and abrasion during repeated high-temperature applications. Each piece undergoes rigorous checks to ensure the 95% alumina content is maintained and that any variance in composition remains within permissible limits.

Our team also conducts comprehensive dimensional assessments to verify the conical form and 1000 mL capacity, as even slight deviations can impact performance in precise laboratory and industrial environments. Frequent inspections at multiple stages, combined with advanced instrumentation, provide assurance that customers receive a consistent and reliable product every time.
