Product FAQ's
Highly polished alumina ceramic sheets are known for their extreme hardness, excellent electrical insulation, and chemical resistance. These high purity alumina sheets offer a smooth surface and minimal porosity, making them ideal for precision applications in electronics, optics, and high-temperature environments.
Yes, both standard and high purity alumina sheets perform well under thermal cycling. They maintain structural integrity across repeated heating and cooling cycles, which is essential for use in kilns, furnaces, and scientific instruments.
Absolutely. Due to their low outgassing and inert nature, alumina ceramic sheets are well-suited for use in vacuum chambers and cleanroom settings. Their purity ensures they won’t contaminate sensitive processes.
Polished alumina plates and sheets are used in semiconductor production, thermal insulation, laser equipment, and as substrates for thin-film deposition. Their versatility also extends to aerospace, medical, and lab applications where stability and durability are required.
To clean alumina ceramic sheets, use a soft cloth or sponge with isopropyl alcohol or deionized water. Avoid abrasive cleaners or scrubbing tools that may scratch the polished surface, especially for high purity alumina sheets used in controlled environments.
Yes. Most suppliers can provide alumina plates and sheets in custom dimensions, shapes, and thicknesses. This allows for tailored solutions in research labs and industrial processes with specific design needs.
