5 FAQs of Corundum Mullite ceramic sagger tray crucible for refractory Kiln with good corrosion

Corundum Mullite ceramic sagger tray crucibles handle high-temperature tasks in refractory kilns. These answers cover common questions.

What materials make these crucibles corrosion-resistant? Corundum Mullite ceramic combines alumina (Al2O3) and mullite (3Al2O3·2SiO2). Alumina offers hardness. Mullite adds thermal shock resistance. The mix creates a dense structure. This slows chemical attacks from molten metals, salts, or acidic gases.

What temperatures can these crucibles withstand? They work in environments up to 1700°C. The material’s low thermal expansion prevents cracks under rapid heating or cooling. This suits processes like metal smelting or ceramic sintering. Exact limits depend on the kiln’s atmosphere.

How do these crucibles resist chemical damage? The low porosity reduces penetration by corrosive substances. Alumina resists acids. Mullite handles alkaline conditions. This dual strength makes them useful in mixed chemical settings. Avoid direct contact with strong fluorides or phosphoric acids. These might degrade the material over time.

How long do these crucibles last? Lifespan varies with use. Proper handling gives 6-12 months in continuous operation. Factors include thermal cycling speed, chemical exposure intensity, and load weight. Inspect for cracks or surface erosion regularly. Replace if thickness drops below 50% of the original.

How to maintain these crucibles? Clean after each use. Remove residue with non-abrasive tools. Preheat slowly before high-temperature runs. Avoid sudden cooling. Store in dry areas to prevent moisture absorption. Do not stack heavy items on unused crucibles. This prevents accidental chipping.
