Title: Crack resistance and atomic structure of Li{sub 2}B{sub 4}O{sub 7} single crystals

Abstract

The nature of destruction of single crystals of lithium tetraborate Li{sub 2}B{sub 4}O{sub 7} under the action of a concentrated load is investigated. It is established that planes of easy crack propagation in Li{sub 2}B{sub 4}O{sub 7} single crystals are the (100), (010), (001), and {l_brace}111{r_brace} planes. It is found that crack propagation occurs in each case along the atomic layers that are linked by bridge oxygen atoms between main structural units (B{sub 4}O{sub 9}) and, therefore, are most weakly bound.
