A Review of using Spray Pyrolysis through Sol-gel
... would be NH4·H2PO4.34,35 Two synthesis routes following the sol-gel process were discussed to show that the pure olivine structure could be formed regardless of the different starting materials. The first method involved dissolving stoichiometric amounts of Li (OH)·H2O, FeC2O4·2H2O and NH4·H2PO4 rea ...

- Form when atoms SHARE electrons instead of transferring them
... Atoms may share one, two, or three pairs of electrons. Atoms will usually share enough electrons so that each atom ends up with a share in EIGHT electrons - the "octet rule" - HYDROGEN will only end up with two electrons! - Some other atoms may end up with more or less than eight electrons ... but w ...

Solid
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice) or irregularly (an amorphous solid such as common window glass).The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.
