5 FAQs of 1700c high temperature Sintered Kiln Corundum Mullite sagger ceramic boat crucible

What is the maximum temperature the 1700°C high-temperature sintered kiln corundum mullite sagger ceramic boat crucible can withstand? The crucible is designed to endure continuous temperatures up to 1700°C, thanks to its composition of corundum (aluminum oxide) and mullite (aluminum silicate). These materials provide exceptional thermal stability, minimizing deformation or degradation even under extreme heat, making it ideal for prolonged high-temperature processes like sintering, calcination, or firing advanced ceramics and metals.

What industries or applications is this crucible best suited for? This crucible is widely used in industries requiring high-temperature processing, such as ceramics manufacturing, metallurgy, electronics, and aerospace. It is ideal for sintering technical ceramics, firing lithium battery materials, heat-treating metal alloys, or annealing glass components. Its chemical inertness and thermal shock resistance also make it suitable for lab research, kiln furnaces, and environments demanding purity and minimal contamination.

How does the durability of corundum mullite compare to other crucible materials? Corundum mullite offers superior durability compared to standard alumina or silicon carbide crucibles. Its blended composition enhances resistance to thermal shock, mechanical stress, and chemical erosion. This results in a longer lifespan, reduced cracking, and lower replacement frequency, even when exposed to rapid temperature fluctuations or corrosive materials like molten salts or reactive gases.

Are there specific handling or usage precautions for this crucible? Avoid abrupt temperature changes to prevent thermal shock. Gradually preheat the crucible to 500°C before exposing it to higher temperatures. Handle with care to avoid mechanical impact, which may cause chipping. Always use tongs or protective gear when moving the crucible at high temperatures, and ensure it is placed on a stable, heat-resistant surface during use.

How should I clean and maintain the crucible after high-temperature use? Allow the crucible to cool naturally to room temperature after use. Remove residue with a soft brush or non-abrasive tool. For stubborn deposits, soak in a mild acidic or alkaline solution, then rinse with water. Avoid harsh mechanical scraping. Regularly inspect for microcracks or wear, and store in a dry environment to prevent moisture absorption, which could compromise performance during reheating.
