Calcium Silicate Blocks Manufacturers in India

One of the significant advantages of calcium silicate insulation blocks is their exceptional heat resistance. They can withstand high temperatures without significant degradation, making them suitable for applications where heat conservation or containment is crucial.

Industries such as petrochemical, power generation, metallurgy, and cement production often utilize these blocks to insulate pipes, vessels, furnaces, and other high-temperature equipment.

The primary ingredients for calcium silicate insulation blocks are calcium and silica sources, along with additives for enhancing specific properties. Calcium oxide (lime) and silica sand are commonly used as the main raw materials. These materials are carefully selected and processed to ensure consistent quality and proper chemical composition.
The raw materials are mixed together in precise proportions to achieve the desired chemical composition of the calcium silicate compound. This mixture is blended thoroughly to ensure uniform distribution of the ingredients.
The mixed raw materials are introduced to water to initiate a chemical reaction known as hydration. During hydration, calcium oxide reacts with water to form calcium hydroxide, which then reacts with silica to create calcium silicate hydrate (CSH) – the main binder in the insulation blocks. This reaction generates heat and causes the mixture to solidify into a cohesive mass.
