Q&A
1-What is ceramic aerogel?
Ceramic aerogel is an advanced insulation material made with ceramic oxides, offering ultra-low thermal conductivity under high-temperature.
2-How high a temperature can ceramic aerogel withstand?
It can operate reliably above 1200 °C, with some formulations stable up to 1350 °C.
3-Can ceramic aerogel stop thermal runaway in lithium-ion batteries?
It provides effective fire barriers and thermal runaway protection in the 700–1000 °C range, outperforming silica aerogels.
4-What is the thermal conductivity of AEG ceramic aerogel?
0.021–0.025 W/m·K at room temperature (25℃),
0.038-0.060 W/m·K at 500℃
5- Is ceramic aerogel flexible or rigid?
it is soft, cuttable, and easy to integrate with mica/ pet sheet
6-Can ceramic aerogel be laminated with other materials?
Yes, it can be packaged with PET, mica, or aluminum foil, and customized with adhesive backing or protective strips.
7-What thicknesses are available?
Typically 1–10 mm
8-Is ceramic aerogel safe and environmentally friendly?
It is inorganic, non-toxic, non-flammable, and manufactured using eco-friendly processes.
