Specification of Customized aluminum oxide alumina Al2O3 ceramic cylindrical corundum crucible for Laboratory

The Personalized Light Weight Aluminum Oxide (Alumina) Al ₂ O ₃ Ceramic Cylindrical Diamond Crucible is a high-performance laboratory tool created for extreme thermal and chemical atmospheres. Crafted from premium-grade alumina (≥ 99% purity), this crucible supplies phenomenal resistance to warm, rust, and mechanical stress, making it ideal for applications such as melting, calcination, sintering, and high-temperature example preparation.

** Product Make-up **: The crucible is composed of ≥ 99% aluminum oxide (Al ₂ O ₃), guaranteeing very little impurities for constant results in sensitive experiments. The high alumina content improves thermal stability, chemical inertness, and architectural stability.

** Physical Features **: Readily available in adjustable dimensions (inner/outer size, elevation, wall density) to fulfill specific lab demands. Criterion dimensions vary from 10 mL to 5000 mL capability. Running temperatures extend from -100 ° C to 1800 ° C, with temporary tolerance as much as 1900 ° C. It displays reduced thermal development (8.6 × 10 ⁻⁶/ K) and high thermal shock resistance (ΔT ≥ 300 ° C), making it possible for fast heating/cooling cycles without breaking.

** Chemical Resistance **: Resists acids, alkalis, molten salts, and many corrosive compounds, except hydrofluoric acid and solid alkalis at raised temperature levels. Non-reactive with steels, alloys, and oxides, making certain example purity.

** Mechanical Strength **: Boasts a Vickers solidity of 15– 18 GPa, compressive stamina ≥ 2000 MPa, and flexural toughness ≥ 300 MPa, making certain sturdiness under mechanical stress and anxiety. Surface area coatings (brightened, glazed, or as-sintered) are customizable to minimize contamination threats.

** Modification Alternatives **: Customized styles include covers, takes care of, spouts, or specialized layers (e.g., platinum). Surface area markings or college graduations can be included for dimension precision.

** Applications **: Suitable for XRF/XRD evaluation, metal/glass melting, ash screening, and semiconductor processing. Suitable with induction furnaces, smother furnaces, and vacuum cleaner settings.

** Quality Assurance **: Each crucible undergoes strenuous testing for density (≥ 3.9 g/cm ³), porosity (≤ 0.5%), and dimensional accuracy. Complies with ASTM, ISO, and hubbub criteria for laboratory safety and security.

** Packaging **: Separately cushioned to prevent damages during transportation. Take care of with treatment as a result of intrinsic brittleness; stay clear of influence or sudden temperature level changes.

This crucible integrates accuracy design with durable product scientific research, providing reliability for innovative research study, quality control, and industrial procedures. Customized requirements are offered upon demand to straighten with unique experimental needs.

5 FAQs of Customized aluminum oxide alumina Al2O3 ceramic cylindrical corundum crucible for Laboratory

What are the key temperature resistance properties of customized Al2O3 ceramic crucibles? Customized Al2O3 ceramic crucibles offer exceptional high-temperature resistance, withstanding continuous use up to 1800°C (3272°F) and short-term exposure up to 2000°C (3632°F). Their thermal shock resistance allows rapid temperature fluctuations of 200–300°C without cracking, depending on the alumina purity (typically 95%–99.9%). Higher-purity alumina enhances chemical stability but slightly reduces thermal shock tolerance, making them ideal for demanding lab processes like melting, sintering, or calcination.

What customization options are available for these crucibles? These crucibles can be tailored in diameter (5–200 mm), height (10–500 mm), and wall thickness (1–20 mm). Additional features include custom lids, pouring spouts, handles, engraved labeling, or surface finishes (polished or textured). Custom shapes, such as tapered or stepped designs, are also possible to suit specific experimental setups or furnace dimensions.

How durable are alumina ceramic crucibles in laboratory environments? Al2O3 crucibles are highly durable due to alumina’s hardness (9 Mohs) and corrosion resistance. They withstand aggressive chemicals, acidic/alkaline fluxes, and abrasive materials, ensuring minimal wear over time. With proper care, they maintain structural integrity for hundreds of heating cycles, outperforming quartz or metal crucibles in longevity under extreme conditions.

What handling and maintenance practices extend the crucible’s lifespan? Avoid sudden temperature changes—preheat gradually and cool slowly. Use tongs compatible with the crucible’s shape to prevent mechanical stress. Clean with non-abrasive methods: soak in dilute acid (e.g., HCl) for residue removal, then rinse with distilled water. Store in dry environments to prevent moisture absorption, which could cause cracking during heating.

What applications are these crucibles best suited for? These crucibles are ideal for high-temperature applications such as metal/alloy melting, glass fusing, ash testing, XRF analysis, and powder sintering. They’re widely used in materials science, metallurgy, and chemistry labs for processes requiring chemical inertness, thermal stability, and contamination-free results. Their customization ensures compatibility with tube furnaces, TGA systems, and induction heating setups.
