Ca2Cu2Si2O7

Ca2Cu2Si2O7 is a calcium copper silicate with the chemical formula Ca2Cu2Si2O7. It belongs to the family of ceramic oxide materials and is composed of calcium, copper, silicon, and oxygen atoms arranged in a silicate framework. The compound is of interest in materials science as a phase that can form in copper-containing silicate systems.

Natural occurrence of this exact composition as a mineral is not well documented; Ca2Cu2Si2O7 is primarily encountered as a synthetic phase produced in laboratory experiments and in high-temperature ceramic processing. It is studied within the broader context of calcium-copper silicate chemistry and the CaO-CuO-SiO2 system.

Synthesis and processing of Ca2Cu2Si2O7 typically involve high-temperature solid-state reactions using stoichiometric amounts of calcium oxide (CaO), copper oxide (CuO), and silicon dioxide (SiO2). The mixture is subjected to heat treatment to promote crystallization and phase formation, which can occur in controlled sintering or annealing steps. In practical terms, it may appear as a crystalline phase in certain glass-ceramics or ceramic formulations designed to explore phase relations in copper-containing silicates.

Crystal structure and properties reported for Ca2Cu2Si2O7 can vary with preparation conditions, and detailed, consensus data for this exact composition are limited. Copper ions in silicate matrices can influence electronic, optical, and, in some cases, magnetic aspects, but specific measurements for this compound are not broadly standardized.

Applications and research focus on Ca2Cu2Si2O7 are primarily within materials science and solid-state chemistry, where its formation, stability, and potential roles in ceramic systems are investigated.
