Cell Lab High-Purity Alumina (Al₂O₃) Cylindrical Crucibles [250 – 2000 mL Capacity]

Cell Lab High-Purity Alumina (Al₂O₃) Cylindrical Crucibles [250 – 2000 mL Capacity]

Large-capacity sintering crucibles for high-temperature metal casting and chemical calcination

General Description

Cell Lab high-purity alumina (Al₂O₃) cylindrical crucibles offer exceptional thermal stability, hardness, and chemical inertness. With a melting point above 1600 °C and purity > 99 %, they are ideal for chemical calcination, ceramic synthesis, metal melting, and powder sintering.

Each crucible is precisely engineered for uniform heating and thermal shock resistance. Optional matching lids are available to minimise contamination and evaporation during high-temperature operations.

Note – Crucibles are classified as consumables and not covered by warranty. For best performance, pre-dry at 105 °C for 2 hours before first use and maintain a heating/cooling rate below 5 °C min⁻¹ (<1200 °C) or 4 °C min⁻¹ (>1200 °C).

Key Features

• High-purity Al₂O₃ (> 99 %) — Ensures superior resistance to chemical corrosion and thermal shock.

• High-temperature tolerance (≤ 1600 °C) — Suitable for sintering, calcination, and metal casting applications.

• Excellent mechanical strength — Resists cracking and deformation under rapid temperature changes.

• Large capacity designs — Available from 250 mL to 2000 mL for laboratory and industrial use.

• Customisable dimensions — Special sizes, wall thicknesses, and lids available upon request.

FAQ

Q1: What is the recommended pre-treatment before using alumina crucibles?
A: Dry the crucible at 105 °C for 2 hours to remove moisture before use.

Q2: How fast can the crucible be heated?
A: Do not exceed 5 °C min⁻¹ below 1200 °C and 4 °C min⁻¹ above 1200 °C to avoid thermal shock.

Q3: Can I request customised sizes or shapes?
A: Yes — we offer custom diameters, depths, and wall thickness upon request.

Q4: Are lids included?
A: Lids are available separately for each capacity option.

Q5: Are these crucibles covered by warranty?
A: As consumables, crucibles are not warranted; please report any quality issues within one week of delivery.
