Specification of 95 99 Alumina Corundum Ceramic Combustion Boat Crucible

This alumina ceramic combustion boat crucible manages high warm. It’s made from 95% to 99% pure alumina. This makes it extremely strong and immune to use. The material is really thick. This thickness quits gases and liquids from dripping with. It keeps your samples safe inside.

The crucible works well in labs and sector. It’s excellent for combustion analysis. You can use it for ashing samples also. It takes care of temperatures approximately 1650 ° C quickly. Its thermal shock resistance is outstanding. This implies it will not fracture if temperatures transform quick. Relocate from hot to cool is risk-free.

Chemical resistance is a key function. Acids and alkalis do not harm it. Bases will not harm it either. This makes it trusted for several chemicals. The surface area is extremely smooth. This smoothness stops samples from sticking. Cleansing is simple after usage. Its shape is a typical boat style. This shape is excellent for holding powders or little solids. It fits typical lab furnaces perfectly.

Measurements are specific. Usual dimensions are around 100mm long, 15mm broad, and 10mm high. Various other dimensions are available as well. You can order customized dimensions if required. The walls are thick enough for stamina. They are thin enough forever warm transfer. This balance guarantees efficient home heating.

This crucible lasts a long period of time. It outmatches less costly materials like porcelain. It endures repeated home heating and cooling cycles. Handle it with care. Stay clear of sharp influences. Clean it with basic lab cleaners. It provides trustworthy efficiency for requiring high-temperature tasks.

5 FAQs of 95 99 Alumina Corundum Ceramic Combustion Boat Crucible

What temperature can these alumina boats handle?
These boats handle very high heat. Pure alumina melts above 2000°C. Our 95-99% alumina boats easily withstand continuous use up to 1700°C. Higher purity means higher temperature resistance. Choose 99% for the most extreme heat.

Why use alumina instead of porcelain?
Alumina beats porcelain for lab work. Alumina resists much higher temperatures. Alumina also fights chemicals better. Acids, bases, and fluxes won’t easily damage it. Porcelain cracks and erodes faster. Alumina lasts longer.

Does sample material stick to the boat?
Smooth surfaces prevent sticking. Our boats have a glassy finish. This finish minimizes sample adhesion. Clean samples release easily after firing. Avoid rough surfaces. Rough surfaces trap material.

Can these boats handle sudden temperature changes?
Avoid big temperature shocks. Alumina resists heat well. Alumina doesn’t like fast heating or cooling. Rapid changes cause stress. Stress leads to cracks. Heat and cool these boats slowly. Follow recommended rates.

How do I clean the boats after use?
Cleaning is straightforward. First, let the boat cool completely. Use warm water and a soft brush. For stubborn residues, soak in dilute acid. Avoid harsh abrasives. Harsh abrasives scratch the surface. Dry thoroughly before reuse.

What chemicals attack these boats?
Strong alkalis pose the biggest risk. Molten hydroxides like sodium hydroxide attack alumina. Certain strong acids can be problematic over time. Fluorine compounds are very damaging. Hydrofluoric acid dissolves alumina. Use other materials for these chemicals.
