Application
- Influence of impurity on the properties of chemically synthesized calcium hydroxide: This study utilized Calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) for the chemical precipitation synthesis of calcium hydroxide at room temperature (P Kumar et al., 2021).
- Study of the effect of calcium nitrate, calcium formate, triethanolamine, and triisopropanolamine on compressive strength of Portland-pozzolana cement: Explored the impact of Calcium nitrate tetrahydrate on the performance of Portland-pozzolana cement (A Derakhshani et al., 2023).
- Calcium nitrate tetra-hydrate-doped polyvinylidene fluoride thin films as potential devices for pressure sensors: Discusses the preparation and potential use of these doped films in sensor applications (KS Hwang et al., 2020).
- Effect of reaction rate on the properties of chemically synthesized calcium hydroxide nanoparticles: Investigates how varying the reaction rate affects the properties of nanoparticles synthesized using Calcium nitrate tetrahydrate (P Kumar et al., 2020).
