Surface area, of crystals

Thus a comparison of the relative surface areas of crystals grown in pure solvent and in solvents containing additives deliberately introduced into the system allows identification of the faces affected by the additive, and subsequently of the crystallographic directions involved in the inhibition process. 

Total surface area of crystals per unit volume ... 

The information in the table shows that the shape of filler particles is determined by their crystal structure and cleavage. The surface area of crystal is increased by milling but it retains the original features of the mineral. This... 

Surface area of crystals. A crystal 1 cm on a side has a surface area of 6 cm. Subdivided into 1000 smaller crystals, each 0.1 cm on a side, the total surface area is increased to 60 cm. ... 

Salting refers to the growth on evaporator surfaces of a material having a solubility that increases with an increase of temperature. It can be reduced or eliminated by keeping the evaporating liquid in close or frequent contact with a large surface area of crystallized solid. 

The porous structure of MCM-41 materials was characterized by their BET surface area, mesopore volume and diameter (Tab.1 and 2). The mesopore volume Vme was obtained as the adsorption (converted to liquid volume) corresponding to the filling of the MCM-41 porous system proper. The external surface area of crystals was estimated from the desorption branch of the hysteresis loop as the surface area of pores larger than the MCM-41 pores proper. The size (diameter) of mesopores was calculated using a tubular model as 4V S where S stands for the BET surface area minus the external surface area.
