Cenosphere from Petra Industries Pvt. Ltd. is a lightweight, inert hollow microsphere composed of alumina and silica, derived as a byproduct of coal fly ash from thermal power plants. The material is available with a particle size range of 5 to 300 micrometers, a density of 0.60 to 0.70 g/cc, and a compressive strength of 105 to 210 kg/cm² (2000 to 4800 psi). Its grey to light grey colour and spherical shape improve flowability and reduce shrinkage in composite applications, while its low oil absorption and high packing factor enhance workability under pressure.
This cenosphere variant is physically hard, rigid, and waterproof, with thermal resistance up to 1500°C, making it suitable for high-temperature applications such as refractories and ceramics. Its inert nature and chemical resistance allow it to function as a filler in cement, polymers, and coatings without reacting with the matrix. The hollow structure provides buoyancy and insulation, reducing the overall weight of formulated products while maintaining structural integrity.
Industrial buyers source cenosphere for use in oilfield drilling fluids, construction materials, and automotive components where lightweight and insulating properties are critical. Petra Industries Pvt. Ltd. supplies the material in bulk bags or loose bulk, with logistics typically arranged via standard container shipments from Indian ports. Buyers should confirm packaging preferences and incoterms to align with their handling and storage capabilities.

Before ordering cenosphere from Petra Industries Pvt. Ltd., buyers should verify the particle size distribution, density, and compressive strength to ensure they meet the requirements of their specific application. Requesting a certificate of analysis (COA) from the supplier will provide documented proof of these critical specifications, which are essential for quality control and consistency in downstream processing.
Logistics for cenosphere shipments from India typically involve containerised transport, with incoterms such as FOB or CIF commonly used. Buyers should confirm the supplier’s ability to arrange shipping from major Indian ports like Mundra or Nhava Sheva, and clarify whether the material is provided in bulk bags or loose bulk. Lead times may vary depending on the volume ordered and the availability of stock at the time of purchase.
Quality checks for cenosphere should include visual inspection for colour consistency (grey to light grey) and spherical shape, as well as laboratory tests for density, compressive strength, and thermal resistance. Buyers may also request additional documentation, such as material safety data sheets (MSDS) and test reports for oil absorption and packing factor, to ensure the material meets industry standards for their intended use.
