Product DescriptionAgricultural special block calcium oxide: soil acid adjustment, sterilization, cost-effective choiceAgricultural special block calcium oxide emerges as a practical and economical solution for modern agricultural needs, particularly in soil acid adjustment and sterilization. Its strong alkalinity enables it to effectively neutralize acidic soils, raising the pH value to an optimal range that promotes robust crop growth. By reacting with water, it not only releases heat to kill harmful pathogens,and weeds in the soil but also improves soil structure, enhancing water and nutrient retention capabilities. Compared to other soil amendments, this block calcium oxide stands out for its high cost-performance ratio—offering long-lasting effectiveness with minimal application rates, thus reducing both input costs and labor intensity for farmers. Whether used in farmland, vegetable gardens or orchards, it serves as a reliable choice to maintain soil health and boost agricultural productivity.SpecificationInnovative DesignKey Features & AdvantagesMain Applications High Purity: Up to 95–98% CaO content Low Impurities: Minimal MgO, Fe2O3, and SiO2 Strong Reactivity: Fast slaking performance Customized Sizes: Powder, granule, or lump form Consistent Quality: Sourced from self-owned mine1.Metallurgy – Desulfurization & slagging agent in steelmaking2.Environmental Protection – Flue gas desulfurization, wastewater pH regulation3.Construction – Soil stabilization, AAC block production4.Chemicals – Calcium hydroxide production, catalyst base5.Pulp & Paper – Lime recovery in kraft pulpingTechnical HighlightsFeatureSpecificationCao contentFrom 85% to 99%SiO2<1.0%Fe2O3<0.3%MgO<1.0%L.O.I(Loss on Ignition)<3.0%Moisture<0.5%(on request)Particle SizeCustomized:100mesh -2000mesh AppearanceWhite power/lumpPacking & DeliveryStandard Export Pack:OEM Services:25kg / 500kg / 1000kg jumbo bags with PE inner linerStore in dry, well-ventilated warehouseKeep away from moisture and incompatible substances Flexible delivery: EXW / FOB / CIF / DDP available Export experience in Asia, Europe, Middle East SGS / COA / MSDS / Reach documents providedAfter Sales ServiceTechnical Support Logistics Follow-upCustomer Feedback SystemFree consultation for usage, storage, and handling.Real-time updates on production and shipping status.Response to any complaint or problem within 24 hours.Company ProfileChangshu Hongyu Calcium Co., Ltd., We own two factories and one limestone mine, allowing us to control the entire supply chain — from raw material to finished product — and ensure long-term stability and cost efficiency.
