    The thermal behavior of a woolly erionite-K sample (Lander County, NV, USA), chemical formula (Ca 2.03 Na 0.73 K 2.52 Mg 0.26)[Al 8.22 Si 27.78 O 71.80]·35.94H 2 O, was investigated in the 303–1173 K thermal range by in situ X-ray powder diffraction. Present data suggest a general thermally-induced volume contraction whose magnitude increases as S i S i + A l ratio becomes smaller.[...]

    Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article.[...]
