Specification of High Temperature Alumina Porcelain Crucible

High Temperature Alumina Porcelain Crucible– Product Specification

Material and Make-up

This crucible is made from high-purity alumina porcelain. The material contains over 99% light weight aluminum oxide (Al two O TWO). This gives the crucible excellent resistance to heat and chemical corrosion. It remains stable also under extreme thermal problems.

Temperature level Resistance

The crucible can handle constant usage at temperatures as much as 1700 ° C (3092 ° F). It will not fracture, warp, or shed architectural toughness within this variety. Short-term exposure to even greater temperatures is additionally feasible without damages.

Physical Residences

Density: About 3.6 g/cm TWO.
Solidity: Very high– withstands scraping and wear.
Thermal development: Low, which decreases stress and anxiety throughout quick home heating or air conditioning.
Porosity: Almost zero– makes certain no absorption of fluids or gases.

Chemical Resistance

The crucible stands up to strike from a lot of acids, antacid, and molten metals. It does not react with usual research laboratory reagents. Nevertheless, it ought to not be used with hydrofluoric acid or solid alkali changes at high temperatures, as these can trigger damage.

Usual Applications

This crucible is commonly made use of in labs and industrial settings for:.
– Melting and integrating samples.
– High-temperature ashing.
– Calcination of products.
– Holding reactive compounds throughout thermal handling.

Readily Available Shapes And Sizes

We offer typical sizes from 10 mL to 200 mL capability. Personalized measurements are likewise available upon request. Each crucible comes with a matching lid to avoid contamination and loss of example throughout home heating.

Handling and Care

Constantly warmth and cool down the crucible slowly to avoid thermal shock. Usage clean tongs when dealing with. Do exempt it to unexpected temperature changes. Store in a dry location away from dust and dampness.

Lab Evaluating and Research Study

High-temperature alumina porcelain crucibles are extensively made use of in labs. Scientists rely on them for melting, heating, or merging examples at really heats. These crucibles take care of warm up to 1700 ° C without breaking or warping. Their chemical inertness makes them optimal for evaluating metals, minerals, and ceramics. They do not react with most acids, antacid, or molten products, so test results remain precise.

Metallurgy and Foundry Job

In steel production, these crucibles hold liquified steels like light weight aluminum, copper, and steel. They resist thermal shock throughout duplicated heating and cooling down cycles. This resilience reduces damage and conserves costs in time. Workers use them in tiny foundries and commercial casting arrangements where purity and stability matter.

Ceramics and Glass Manufacturing

Ceramic artists and glassmakers make use of alumina crucibles to melt raw materials cleanly. The crucibles help preserve regular shade and texture in finished items. Since they launch no impurities, the last lusters or glass items look clear and consistent. They additionally sustain high-temperature sintering processes required for technical porcelains.

Environmental and Quality Control Labs

Government and personal laboratories utilize these crucibles for ash web content analysis. Examples like coal, oil, or food are melted entirely inside the crucible. The deposit left is measured to inspect quality or compliance. Due to the fact that alumina porcelain stays steady under severe warmth, it ensures repeatable, credible data.

Key Benefits:
These crucibles supply exceptional thermal stability, strong resistance to deterioration, and lengthy service life. They are very easy to tidy and reuse. Their smooth surface protects against example sticking, which helps stay clear of cross-contamination between examinations. For any job needing high heat and product purity, high-temperature alumina porcelain crucibles deliver reputable efficiency.

5 FAQs of High Temperature Alumina Porcelain Crucible

Frequently Asked Questions About High-Temperature Alumina Porcelain Crucibles

What is a high-temperature alumina porcelain crucible made of?

This crucible is made from high-purity aluminum oxide (alumina). The material is fired at very high temperatures. This gives the crucible strong heat resistance and chemical stability.

What temperature can it handle?

It can safely work at temperatures up to 1700°C (3092°F). Some grades may even go higher. Always check the exact rating for your specific model before use.

Can it be used with strong acids or bases?

Alumina crucibles resist most chemicals well. They hold up against many acids and molten metals. However, avoid using them with hydrofluoric acid or strong alkalis like sodium hydroxide at high heat. These can damage the crucible over time.

How do I clean and store it?

Let the crucible cool down fully after use. Clean it with soft brushes or mild solvents. Do not use abrasive tools—they can scratch the surface. Store it in a dry place away from dust and moisture. Keep it on a clean shelf or in a protective case.

Why choose alumina over other ceramic crucibles?

Alumina offers better thermal shock resistance than many other ceramics. It also has low reactivity, which means it won’t easily mix with your samples. This makes it ideal for precise lab work, ash testing, and high-heat industrial processes. Its long service life and reliability make it a smart choice for repeated high-temperature use.
