Zirconia Crucible

Advantages

1. High temperature resistance: The melting point is about 2700°C, and it can work stably for a long time at more than 2000°C, which is far higher than alumina and quartz crucibles.

2. Thermal shock resistance: By adding stabilizers such as yttrium oxide (Y₂O₃), a partial stable structure (such as Y-TZP) is formed to reduce the risk of rupture caused by sudden temperature changes.

3. Chemical inertness: It is inert to most acids, alkalis and molten metals (such as gold and platinum), especially suitable for processing highly active materials.

4. Low thermal conductivity: The slow heat transfer characteristics help the sample to be heated evenly and reduce thermal stress.

Parameters

Applications

1. Materials science: synthesis of high-purity ceramics, single crystal growth (such as laser crystals), high-temperature sintering (such as silicon nitride, silicon carbide).

2. Precious metal processing: melting platinum, rhodium, gold, etc., to avoid metal contamination (better than graphite crucible).

3. Analysis and testing: used for sample pretreatment of instruments such as XRF and ICP-MS to ensure detection accuracy.

4. Nuclear industry: processing radioactive materials, because its radiation resistance is better than ordinary ceramics.

5. Special glass: melting optical glass and high-temperature resistant glass fiber.
