Overview of Mullite Crucible

Mullite crucibles are made from a high-performance ceramic material composed primarily of alumina (Al₂O₃) and silica (SiO₂). Known for their excellent thermal stability and mechanical strength, mullite crucibles are widely used in high-temperature applications such as melting metals, glass, and ceramics. They offer superior resistance to thermal shock and chemical attack, making them indispensable in both laboratory and industrial settings.

Features of Mullite Crucible

Thermal Shock Resistance: Exceptional ability to withstand rapid temperature changes without cracking.
High Mechanical Strength: Strong and durable, even at elevated temperatures.
Chemical Stability: Resistant to most chemicals, ensuring minimal contamination during processes.
Temperature Range: Can operate effectively at temperatures up to 1650°C.
Low Thermal Expansion: Minimal expansion or contraction with temperature changes, ensuring dimensional stability.
Non-Reactive: Does not react with the materials being processed, preserving sample purity.
Versatility: Suitable for a wide range of applications including metallurgy, glass manufacturing, and laboratory experiments.

Specifications of 6.4x8mm mini alumina thermal analysis crucibles or TGA samples pans

These 6.4x8mm mini alumina crucibles are essential for thermal analysis. They are specifically designed for TGA (Thermogravimetric Analysis). The small size is critical. It fits perfectly into sensitive microbalances. The crucibles measure 6.4 millimeters in diameter. They stand 8 millimeters tall. This compact form uses minimal sample material. That saves costs. It also improves instrument sensitivity.

Alumina ceramic is the key material. It offers high purity. This purity prevents unwanted reactions with samples. Alumina is chemically inert. This inertness ensures accurate results. Crucibles won’t contaminate your sample. Samples won’t interact with the pan material. Data stays clean and reliable.

These pans handle extreme heat exceptionally well. They withstand temperatures up to 1750°C (3182°F). This high temperature tolerance suits demanding applications. They perform consistently under thermal stress. The material resists thermal shock. Sudden temperature changes cause less cracking. Pans last longer.

The flat bottom design is important. It ensures stable placement on the TGA sample holder. Good contact is vital for proper heat transfer. Heat flows evenly to your sample. You get precise temperature readings. The open top allows gases to escape freely. This is crucial for reactions involving mass loss. You see the true mass change.

These mini crucibles hold a small volume. Typical capacity is around 100 microliters. This suits powdered samples or tiny solids. Their white color helps with some instrument optics. Alumina pans are reusable. They clean easily after most analyses. This reduces waste and cost per test. They provide a stable, inert platform for your samples. Scientists rely on their performance for critical thermal data.

Applications of 6.4x8mm mini alumina thermal analysis crucibles or TGA samples pans

These tiny 6.4x8mm alumina crucibles are essential for thermal analysis, especially Thermogravimetric Analysis (TGA). Their small size solves a big problem. Scientists often work with very limited sample amounts. Think expensive catalysts, precious biological materials, or just a speck of powder. These mini pans hold just milligrams of material effectively. This precision is crucial. It ensures accurate weight change measurements during heating or cooling cycles.

Alumina ceramic is the key material. It withstands extremely high temperatures easily. Many tests run above 1000°C. Alumina handles this heat without softening or reacting. This stability is vital. It prevents the pan itself from interfering with the sample’s weight loss data. Alumina is also chemically inert. It doesn’t react with most samples. This avoids unwanted side reactions skewing the results. You get cleaner, more reliable data.

These crucibles are perfect for demanding applications. They are ideal for analyzing polymers. Polymers decompose at specific temperatures. The inert alumina won’t catalyze reactions. Pharmaceutical researchers rely on them. Drug substances are often scarce. The small pan size conserves valuable material. Catalyst development uses them heavily. Catalysts are tested under high heat. The alumina withstands the conditions. Studying nanomaterials is another key use. Nanomaterials require minimal sample sizes. The mini pans accommodate this perfectly. Even analyzing ash content in fuels benefits. The high temperature tolerance ensures complete combustion.

Their design minimizes heat transfer issues. The small mass heats evenly. This provides consistent temperature across the sample. Consistent temperature leads to sharper, clearer thermal events on the data curve. Handling is straightforward. They fit standard TGA autosamplers. This allows automated, high-throughput testing. Their robustness means they are reusable. Clean them thoroughly between runs. This saves costs over time.

5 FAQs of 6.4x8mm mini alumina thermal analysis crucibles or TGA samples pans

Here are five common questions about our 6.4x8mm mini alumina thermal analysis crucibles or TGA sample pans.

What exactly are these small crucibles used for? These tiny crucibles hold solid or powder samples during thermal analysis. You put them inside instruments like TGA machines. The machine heats the sample inside the crucible. This heating shows how the sample’s weight changes with temperature.

Why is alumina the material used? Alumina handles high heat very well. It stays stable and doesn’t react with most samples. Alumina crucibles won’t melt or break down easily under the intense heat of testing. This gives reliable results. Other materials might react or melt.

How hot can I safely use these crucibles? These mini alumina crucibles work reliably for temperatures up to 1650°C (about 3000°F). They are made for standard TGA experiments. Do not exceed this temperature limit. Going hotter could damage the crucible or ruin your test.

How much sample fits inside? The small size limits the sample amount. You can typically fit between 5 milligrams and 50 milligrams of material. This depends on the sample’s density. Use enough sample for a good signal. But avoid overfilling the crucible. Too much sample might cause spillage or uneven heating.

Can I clean and reuse these crucibles? Yes, you can usually clean them for reuse. After your test, let the crucible cool completely. Remove any leftover sample residue carefully. You can wash it with solvents or use a furnace cycle to burn off organics. Check the crucible for cracks or damage before using it again. Damaged crucibles give bad results.
