Heavy metals (elements with a specific density >5 g [mL.sup.-1]; (Morris 1992)) and metalloids that occur in the input material for pyrolysis become concentrated during carbonization, because of volatilization of gaseous carbon products (syngases), and a corresponding mass loss of the residual solid material (Brown et al.
Metalloids | Encyclopedia
METALLOIDS CONCEPT The term "metalloid" may sound like a reference to a heavy-metal music fan, but in fact it describes a small collection of elements on the right-hand side of the periodic table. Forming a diagonal between boron and astatine, which lies four rows down and four columns to the right of boron, the metalloids are six elements that display qualities of both metals and nonmetals.
