Graphite Black Block
Natraj Stonex Pvt. Ltd. supplies graphite black blocks composed of natural or artificial graphite with a high carbon content ranging from 95 % to 99 %. The product is marketed for use in refractory linings, furnace components and industrial flooring, and is offered in standard block dimensions suitable for bulk handling. The listing does not provide a fixed minimum order quantity, instead indicating that the blocks are available for global trade.
Typical specifications for high‑carbon graphite blocks include a carbon purity of 95‑99 %, a bulk density of about 1.8 g cm⁻³, and a compressive strength in the region of 180‑220 MPa. Thermal conductivity generally falls between 120 and 160 W m⁻¹ K⁻¹, while the material exhibits low moisture absorption, making it stable under repeated heating cycles. These industry‑standard values are widely accepted for refractory applications and ensure reliable performance in demanding environments.
The primary market comprises steelmakers, foundries and construction firms that require durable refractory components. Prospective buyers should request the supplier’s test certificates, verify the block dimensions and tolerances, and discuss packaging options such as wooden pallets or steel drums. Pricing, lead‑time and payment conditions are not disclosed in the public data and must be negotiated directly with Natraj Stonex.
