2011-2-26 strontium oxide is a solid at room temperature. Because it is an ionic compound it has a very high melting point. In general, ionic compounds (a metal bonded to a nonmetal) are strongly bonded intermolecularly which makes them harder to separate from one another and keeps them in a solid state unless there are more extreme conditions.

2007-11-28 Potassium is solid at room temperature. It is odorless. In pure form, potassium is very hazardous. Because it is an alkaline metal, it will react very strongly with anything it can, but the reaction that concerns us the most is with water. Placed in water, it will react at a very fast rate, to produce potassium hydroxide and hydrogen gas.

2003-7-18 Zinc nitrate precipitated with NaOH solution at room temperature under double-jet conditions produced micrometric zinc oxide particles with ellipsoid or starlike morphology separated by only a slight variation of pH (9.5 and 10.5, respectively). The formation kinetics of starlike particles was followed by SEM observations, suggesting that they result from a solid-state transformation of the ...
