Specifications of Lab Melting Used Fused Silica Quartz SiO2 Ceramic Crucible Cup

This fused silica quartz crucible handles extreme heat in lab melting. Pure SiO2 makes it. That means over 99% purity. Impurities stay very low. This crucible won’t contaminate your materials. It works at very high temperatures. You can use it up to 1700°C. Some grades go even higher. It handles sudden temperature changes well. This is thermal shock resistance. You don’t need to worry about cracking fast. The crucible fights chemical attack. Acids and bases won’t easily damage it. Molten metals react little with it. The surface stays smooth and glass-like. This stops material sticking. Cleaning becomes easier. The crucible looks clear or milky white. You can see your melt inside. It comes in many sizes. Common volumes are 10ml, 25ml, 50ml, 100ml. Larger sizes are available too. Wall thickness stays consistent. This helps heat spread evenly. Standard shapes are tall form or low form. Find the shape fitting your furnace. The crucible has a flat bottom. This gives stable placement.

Applications of Lab Melting Used Fused Silica Quartz SiO2 Ceramic Crucible Cup

Lab melting crucibles made from fused silica quartz are essential tools. They handle very high temperatures easily. These crucibles work well up to 1700°C. They also resist sudden temperature changes without cracking. This makes them safe for many heating and cooling jobs.

Their main job is melting glass. Glassmakers need pure materials. Fused silica quartz is very pure. It won’t add bad stuff to the melted glass. This keeps the glass clear and strong. The crucible itself lasts a long time under the heat.

Metal workers use these crucibles too. They melt precious metals like gold and silver. The crucible won’t leak or react with the metal. This means the metal stays pure. Jewelers and metal recyclers rely on this. It saves money and prevents waste.

These crucibles are important in science labs. Chemists need containers that don’t interfere. Fused silica quartz is inert. It won’t mix with chemicals being melted or studied. This gives accurate results. Researchers trust it for critical experiments.

The electronics industry uses them for making special materials. They melt compounds for semiconductors and optics. The crucible’s purity is key here. Any contamination ruins the final product. Fused silica ensures the material stays clean.

These crucibles are tough. They resist most acids and last through many uses. This makes them a good investment. They perform reliably in demanding situations. Factories and workshops choose them for heavy-duty melting tasks.

5 FAQs of Lab Melting Used Fused Silica Quartz SiO2 Ceramic Crucible Cup

What exactly is fused silica quartz?
Fused silica quartz is pure silicon dioxide (SiO2). It’s melted at very high temperatures. This creates a solid glass-like material. Fused silica has excellent properties for crucibles.

How hot can I use this crucible?
Fused silica crucibles handle very high heat. They work well up to 1100°C (2012°F). Don’t use them above 1250°C (2282°F). Going hotter risks sudden cracking. Always check the specific crucible’s rating.

What chemicals won’t damage it?
Fused silica resists many things. It handles most acids well. Hydrofluoric acid and strong alkalis damage it. Phosphates can also cause problems. Avoid these chemicals to keep your crucible safe.

How do I clean it after use?
First, let the crucible cool completely. Remove any leftover solid material gently. Soak it in a suitable acid bath, like diluted hydrochloric acid. Rinse it thoroughly with distilled water after. Dry it completely before storing or reusing.

Can I reuse this crucible many times?
Yes, fused silica crucibles are reusable. Their lifespan depends on your use. Extreme temperatures or harsh chemicals shorten it. Inspect the crucible carefully before each use. Look for cracks or deep etching. Discard it if you see any damage.
