Product Description Product DescriptionSEPPE Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their bulk density is about 0.4-0.8 g/cm3, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.

High refractoriness:Cenosphere (Main SiO2 and Al2O3)have extremely high refractoriness, generally reaching 1600-1700 degrees Celsius, making it an excellent high-performance refractory material.2. Lightweight, thermal insulation:Cenosphere has thin and hollow walls and a semi-vacuum in the cavity. There is only a trace amount of gas (N2, H2, CO2, etc.), and the heat conduction is extremely slow and minimal.3. High hardness and high strength:Because Cenosphere is a hard glass body formed from the silicon-aluminum oxide mineral phase (quartz and mullite), the hardness can reach Mohs 6-7, the static pressure strength is as high as 70-140MPa, and the true density is 2.10-2.20 g/cm3.4. Fine particle size and large specific surface area:The natural particle size of Cenosphere is 1-250 microns. The specific surface area is 300-360g/cm2, which is similar to cement.5. Excellent electrical insulation:Cenosphere's resistance increases with the increase of temperature. This advantage is not available in other insulating materials.Packaging & ShippingPacking: 600kg big jumbo bags with pallets, 2 bags on 1 pallet.FAQWhat is your MOQ?One full container (25-28tons). More quantity you required , better price we can offer for you.What is the leading time?That depends on order quantity. Generally it takes 10-15 days for one full container. How can I get samples to check the quality?We can provide the samples free for you, but the express cost will be on your account. What is your payment term?50% T/T in advance, and balance payment at sight copy of BL. Letter of credit is also available.
