Specification of Alumina Ceramic Crucible Alumina Corundum Ceramic Crucible

Alumina ceramic crucibles are made from high-purity alumina (Al ₂ O SIX), normally including over 99% alumina. These crucibles deal with severe warm, withstanding temperatures as much as 1800 ° C. They resist thermal shock, suggesting unexpected temperature adjustments cause minimal damage. Their low thermal expansion rate avoids breaking throughout rapid heating or air conditioning. The product’s solidity ranks around 9 on the Mohs scale, making it highly wear-resistant. Density arrays in between 3.8 and 3.9 g/cm THREE, guaranteeing structural security under tension. High mechanical strength enables them to withstand heavy tons without warping.

Alumina crucibles show strong chemical resistance. They hold up against destructive acids, antacid, and molten metals. Hydrofluoric acid and strong alkaline services are exemptions, as they may damage the product. The non-porous surface stops contamination, making these crucibles ideal for lab job or high-purity procedures. They are electrically protecting, suitable for applications needing minimal conductivity.

These crucibles are widely utilized in laboratories, commercial heaters, and metal processing. Usual applications include melting metals like platinum or gold, sintering advanced porcelains, and assessing products at heats. Industries such as semiconductors, aerospace, and drugs rely upon their reliability. Custom shapes and sizes are offered, including cylindrical, cone-shaped, or rectangle-shaped designs. Some designs include lids or pouring spouts for specialized jobs.

Surface area coating alternatives vary. Sleek finishes minimize adherence of molten products. Harsh surfaces enhance insulation or structural bonding. Crucible walls can be readjusted in density for far better thermal performance or mechanical support. High-purity alumina guarantees very little interaction with examples, vital for research or quality assurance.

Correct handling extends life span. Avoid mechanical effects to avoid cracking. Progressive pre-heating gets rid of wetness and decreases thermal anxiety. Cleaning with light cleaning agents or ultrasonic tools preserves efficiency. These crucibles outshine options like quartz or graphite in high-temperature security and chemical resistance. Their toughness reduces substitute costs sought after environments.

Personalization meets particular requirements. Manufacturers readjust alumina content for stabilizing cost and efficiency. Reduced alumina qualities (e.g., 85% or 95%) serve much less extreme conditions. Higher qualities prioritize pureness and thermal properties. Technical assistance aids pick the right crucible for every application.
