Precision-ground Quick Lime Powder (CaO 85%–92%) at 325 mesh with 30 µm average particle size and 210°C exotherm. Manufactured near Jodhpur, Rajasthan for plastics, rubber, pharmaceuticals, adhesives, ceramics, and specialty industrial applications.
Quick Lime Powder is Quick Lime (CaO) precision-ground to 325 mesh (approximately 30 µm average particle size). The fine particle size significantly increases surface area and reaction rate, critical for specialty industrial applications requiring uniform, controlled reactivity.
Shreenath Metchem's Quick Lime Powder achieves 85%–92% CaO with low MgO (≤1.5%) and low SiO₂ (≤1.0%), among the cleanest fine lime grades available. The high exotherm value of 210°C confirms vigorous, complete reactivity. This product is designed for manufacturers in plastics, rubber, pharmaceuticals, adhesives and sealants, and ceramics who require a reliable, high-purity fine calcium oxide.
Injected as fine powder into molten steel to remove sulphur before casting. The 325-mesh fineness maximises reaction surface area, enabling faster and more complete desulphurisation.
Fine CaO powder is blown into liquid steel using a carrier gas. The very small particle size creates a large surface area for reaction, so sulphur is removed quickly and efficiently. This produces cleaner, higher-grade steel and the 325-mesh fineness is specifically what makes this desulphurisation process work effectively.
Used to produce calcium salts including calcium propionate, calcium acetate, and calcium gluconate for food, pharmaceutical, and industrial use. High purity is essential as minor impurities directly affect product quality and reaction yield.
Fine CaO with 85%–92% purity reacts with organic acids to form calcium salts. Even small impurities can affect the purity and yield of the final product. We supply high-purity fine lime with consistent CaO content and low impurity levels for reliable batch production.
Applied to contaminated industrial sites to neutralise acidic soils and immobilise heavy metals. The 325-mesh grade distributes evenly through soil for consistent remediation results.
Fine CaO reacts with moisture in contaminated soil, quickly raising the pH and causing dissolved heavy metals to solidify into safe, insoluble forms. The 325-mesh grade spreads more evenly through the soil, giving more uniform treatment and requiring less lime per tonne of contaminated material treated.
Used for precise pH control during API synthesis and pharmaceutical intermediate manufacturing. Small deviations at critical stages can affect the purity, form, or safety of the final drug.
In medicine production, small changes in pH during a reaction affect the purity, form, and safety of the drug. CaO gives controlled, predictable results. Our pharmaceutical-grade batches are tested for heavy metals, arsenic, and contaminants to meet the strict standards required for drug manufacturing.
Added to PVC, rubber, and tyre compounds to neutralise processing acids, support vulcanisation, and improve tensile strength. Acts as a desiccant, absorbing trace moisture that causes weak spots in cured products.
In PVC, fine CaO (325 mesh) disperses evenly and absorbs acid released during high-temperature processing, preventing equipment damage and product discolouration. In rubber and tyre manufacturing, CaO acts as an acid acceptor during sulphur vulcanisation and absorbs moisture that can cause bubbles or weak spots in cured rubber. Fine particle size ensures uniform dispersion in both applications.
Used in ceramic glazes and glass batches to improve melting behaviour, mechanical strength, and surface finish. Fine 325-mesh grinding ensures uniform mixing and consistent quality in fired products.
In ceramic glazes, CaO lowers the temperature at which the glaze melts and flows smoothly. In glass production, it improves durability and chemical resistance. Fine 325-mesh grinding ensures it mixes uniformly into the batch, giving consistent glaze quality and fewer surface defects in fired pieces.
Used in sugar mills and grain processing where food-safe lime with full batch traceability is required. Test certificates are supplied with every delivery for food safety compliance.
In sugar mills, it's dissolved to make clarifying lime for juice treatment. In traditional grain processing, dilute lime solution softens the grain and improves its nutritional value. Our food-grade batches are tested for heavy metals and come with batch certificates for full traceability in food manufacturing.
Added to anti-corrosion paints and primers to keep the coating alkaline at the steel surface, slowing rust formation. Also used as a functional filler that adds body and opacity to the finished coating.
Fine CaO makes the coating slightly alkaline where it touches the steel, slowing down corrosion from starting under the paint film. It also works as a low-cost filler that adds body and opacity to the coating. Fine particle size ensures it stays evenly distributed without settling at the bottom of the paint.
Added to polyurethane and silicone sealants to absorb trace moisture and prevent premature curing. The fine particle size ensures smooth, lump-free dispersion throughout the formula.
In polyurethane and silicone sealants, fine CaO absorbs trace moisture inside the formula that would otherwise trigger early curing. This extends working time and shelf life. The fine particle size is important — it ensures the CaO disperses evenly without forming lumps inside the adhesive.
Reacted with fly ash or sand in autoclaves at 180°C to produce the calcium silicate hydrates responsible for AAC block strength, thermal insulation, and fire resistance.
CaO reacts with reactive silica in fly ash or sand under autoclave conditions to form tobermorite, the mineral phase responsible for AAC block compressive strength. Fine quick lime powder disperses more uniformly in the slurry mix, ensuring consistent reaction across the block and predictable strength output per batch.
