5 FAQs of 95% Al2o3 White Glazed Ceramic Feedthrough Insulator Fine Alumina Beads for Electric Heating

Here are five common questions about our 95% Al2O3 White Glazed Ceramic Feedthrough Insulator Beads for electric heating:

What are these ceramic beads made of?
These beads consist mainly of alumina. The composition is 95% Al2O3. This high purity makes them very strong. It also gives excellent electrical insulation. The white glaze coating adds a smooth finish. This finish seals the surface. It improves resistance to contaminants.

How much heat can they handle?
These alumina beads withstand extreme temperatures. They operate reliably up to 1500°C (2732°F). This high heat tolerance is crucial. Electric heating elements get very hot. The beads won’t crack or degrade easily. They manage thermal stress well.

Where are they typically used?
You find these insulators in heating elements needing electrical feedthroughs. They isolate live electrical wires. This isolation happens where wires pass through furnace walls or metal casings. Common uses are industrial furnaces, kilns, laboratory ovens, and other high-temperature electric heaters. They prevent short circuits.

Why choose alumina over other materials?
Alumina offers distinct advantages. Its mechanical strength is superior. It resists wear and chemical corrosion much better than plastics or lower-grade ceramics. The high dielectric strength stops current leakage effectively. Alumina lasts longer under tough conditions. This reliability reduces replacement frequency. It saves costs over time.

How should they be handled during installation?
Handle the beads carefully. Avoid dropping them or causing strong impacts. Chips or cracks can weaken performance. Ensure the wire passage hole is clean. Match the hole size correctly to your wire diameter. A snug fit is necessary. It prevents movement and maintains good electrical isolation. The glaze helps prevent moisture absorption.
