  • The Initial Stages of Template-Controlled CaCO3 Formation

    Mar 13, 2009 · Biogenic calcium carbonate forms the inorganic component of seashells, otoliths, and many marine skeletons, and its formation is directed by an ordered template of macromolecules. Classical nucleation theory considers crystal formation to occur from a critical nucleus formed by the assembly of ions from solution. Using cryotransmission electron microscopy, we found that template

  • Is concrete bad for the environment? TheGreenAge

    To make cement, limestone (calcium carbonate CaCO3) is heated to temperatures approaching 10000C, along with other feedstock materials such as clay (which contains silicates). At this temperature, the limestone (and other feedstock) breaks down into Calcium Oxide (known as Lime CaO), Silicon Oxides and Carbon dioxide.
