Description

Dicalcium Silicate is a key inorganic compound with the chemical formula Ca₂SiO₄, widely recognized for its role as a primary mineral phase in Portland cement clinker. Its controlled synthesis and purity make it a valuable material beyond construction, serving as a functional additive and reactive precursor in advanced industrial processes. This product is essential for manufacturers and R&D facilities in the ceramics, refractory, and specialty construction materials sectors seeking consistent, high-quality raw materials.

Application

• Cement and Construction Materials: A fundamental mineral component (Belite) in Portland cement, contributing to long-term strength development.
• Refractory and Ceramic Production: Used as a stable calcium silicate phase in high-temperature linings, molds, and technical ceramics.
• Biomedical and Dental Applications: Investigated as a bioactive component in calcium phosphate silicate bioceramics for bone graft substitutes and dental cements.
• Stabilization and Solidification (S/S): Employed in the chemical immobilization of heavy metals in contaminated soils and industrial wastes.
• Advanced Material Synthesis: Acts as a precursor for the sol-gel synthesis of other silicate materials and as a catalyst support.
• Agricultural and Horticultural Amendments: Utilized as a source of slowly available calcium and silicon for soil conditioning in specialty agriculture.

Quality Control

Our Dicalcium Silicate is produced under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification and spectroscopic methods for composition. While we offer standard technical and research grades, production can be aligned with specific customer requirements. A Certificate of Analysis (COA) detailing purity, phase composition, and physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect reactivity.
