WhiteSpice Chemical Sets the Standard for Silica Manufacturing in India

Whitespice Chemicals are manufacturers of Micro Silica – a mineral admixture which has very fine silicon dioxide.
Micro Silica is produced after processing special grade Rice husk ash. This is shorted, pulverized, air classified and packed in specified packing for ease of handling the material at site. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240,EN 13263.
On adding Micro Silica to the cementatious mix, the resultant concrete has more of strong calcium-silicate hydrates and less of the weak and easily soluble calcium hydroxides than the normal concrete mix. As Micro Silica particles are small they disperse among and separate the cement particles and this results in fine, uniform mix that has higher compressive, flexural, and bond strength. Silica fume also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways, runways and saltwater bridges.

Whitespice Chemicals – Manufacturers of Biomass Pellets
Whitespice Chemicals are leading manufacturers of Biomass Pellets – an eco-friendly renewable fuel made from agricultural and forestry residues. Biomass Pellets are produced after processing raw biomass materials such as sawdust, rice husk, bagasse, or agro-waste. These are dried, pulverized, compressed, and packed in uniform sizes to ensure ease of storage, handling, and feeding into modern combustion systems. Standard specifications for biomass pellets in energy applications follow guidelines such as ENplus, ISO 17225-2, and local renewable energy norms. When added to industrial boilers, power plants, or heating systems, Biomass Pellets provide a high calorific value with low ash content, making them an efficient substitute for coal and other fossil fuels. The pelletization process ensures uniform density, size, and moisture levels, which results in steady combustion, higher thermal efficiency, and reduced emissions. Compared to loose biomass, pellets offer significantly better handling, reduced transportation costs, and consistent energy output. Biomass Pellets also play a crucial role in reducing carbon footprints, as they are carbon-neutral – the CO₂ released during combustion is nearly equal to the CO₂ absorbed by the plants during growth. This makes them an ideal green fuel for industries, residential heating, commercial establishments, and large-scale energy projects, especially in regions aiming for sustainable and low-emission energy solutions.

Fine grinded rice husk ash granules of selected composition is spray dried to 120-180 micron. This is an effective tundish cover for insulation on slag free molten steel in continuous casting. It is an effective medium to retain that minimum superheat necessary for a smooth casting operation by preventing radiant heat loss from the surface of the molten steel. Using RHA in its granular form prevents air pollution, reduces wastage, insulation and excellent spreadability.
