Superior Thermal and Structural Performance

Calcium silicate offers outstanding thermal insulation with a low thermal conductivity (0.0350.07 W/mK) and can withstand high service temperatures up to 1100C. Its high compressive strength and smooth surface finish make it ideal for both structural and refractory applications where durability and performance are paramount.

Versatile Applications in Industry

Thanks to its excellent resistance to most acids and insulating properties, calcium silicate is widely used in construction, chemical processing, and fireproofing systems. It serves as a core material for thermal insulation, pipe encasement, boards in building interiors, and as a protective lining in industrial furnaces.

FAQs of Calcium Silicate:

Q: How is calcium silicate typically used in construction and insulation?

A: Calcium silicate is utilized for thermal insulation in buildings, as fireproofing boards, and for encasing pipes. Its excellent insulating properties and high compressive strength make it a preferred material for areas requiring durability and resistance to high temperatures.

Q: What benefits does calcium silicate offer as a refractory material?

A: As a siliceous refractory, calcium silicate delivers stability at elevated temperatures (up to 1100C) and maintains its structural integrity in demanding environments, making it suitable for lining industrial furnaces and reactors.

Q: When should calcium silicate not be used?

A: Calcium silicate exhibits good resistance to most acids but should be avoided in environments exposed to hydrofluoric acid or strong alkalis, as these can degrade the materials performance and structure.

Q: What is the process for manufacturing calcium silicate products?

A: Calcium silicate products are manufactured by reacting lime (CaO) with silica (SiO2) under controlled conditions. The mixture is shaped into boards, blocks, or pipes, and then cured to achieve the desired strength and porosity.

Q: Where is calcium silicate commonly sourced and supplied?

A: Calcium silicate is widely processed and supplied in India by manufacturers, exporters, distributors, and traders who provide various forms, including powder, blocks, boards, and pipes for industrial and construction use.

Q: What forms and grades of calcium silicate are available?

A: Calcium silicate is available in several formspowder, board, blocks, and pipeswith a high purity of at least 90%. These are tailored for specific industrial, insulation, or construction applications based on strength and density requirements.

Q: How does calcium silicates low moisture content and high porosity benefit its performance?

A: With less than 1.5% moisture content and porosity ranging from 6070%, calcium silicate provides efficient thermal insulation, resists water absorption (<10%), and maintains consistent performance in humid or high-temperature settings.
