noun
crushability; breakability; friability
Technical term used in materials science, engineering, and geology to describe how easily a solid material can be crushed, broken, or crumbled. Often used in contexts such as soil, rock, or manufactured materials.
この岩石の破砕性を調べるために、圧縮試験を行った。
We conducted a compression test to examine the crushability of this rock.
土壌の破砕性が高いと、耕作が容易になる。
High friability of the soil makes cultivation easier.
脆性 (brittleness) is a related material property, but it specifically describes sudden fracture without significant deformation, whereas 破砕性 is a broader term for crushability or friability.
Compound of 破砕 (はさい, 'crushing') + 性 (せい, 'property, nature'). The word is a modern technical coinage, likely from the early 20th century, following the pattern of many scientific terms formed with 〜性.
