Corundum does not exhibit cleavage; instead, it has a conchoidal to uneven fracture. Cleavage refers to the tendency of a mineral to break along specific planes of weakness, while corundum's strong crystal structure results in a lack of such planes. Therefore, when corundum breaks, it does so irregularly rather than along defined lines.
What else can I help you with?
What is the cleavage of corundum?
Corundum has a basal cleavage, meaning it cleaves parallel to its basal plane. This cleavage is often poor and can be difficult to observe.
Is shale fracture or cleavage?
the cleavage is Poor
Dose sapphire have a cleavage break or a fracture?
Sapphire has a mixture of both cleavage and fracture characteristics. It has poor cleavage in one direction and conchoidal fracture, which means it breaks with smooth, curved surfaces similar to glass.
Does quart have a cleavage or a fracture?
Quartz has a conchoidal fracture. It does not have a cleavage plane.
Does silver have cleavage or fracture?
Silver has neither cleavage nor fracture because it is malleable and ductile, meaning it can be shaped and stretched without breaking along specific planes like cleavage or irregularly like fracture.
What is the cleavage of corundum?
Corundum has a basal cleavage, meaning it cleaves parallel to its basal plane. This cleavage is often poor and can be difficult to observe.
Does quartz have cleavage or a fracture?
Quartz does not have cleavage. However, it does have fracture. Its fracture is conchoidal.
Does garnet have cleavage or a fracture?
it has no cleavage
Does garnet have cleavage or fracture?
it has no cleavage
Is gypsum fracture or cleavage?
cleavage
Is gold cleavage or fracture?
Fracture
Does hematite have fracture or cleavage?
Hematite has a characteristic fracture, meaning it breaks irregularly with rough or jagged edges and no smooth cleavage planes.
Is shale fracture or cleavage?
the cleavage is Poor
What are the eight ways to identify corundum?
THE EIGHT WAYS TO I.D. A MINERALThe eight ways to identify a mineral such as corundum are 1 hardness 2 crystal shape 3 special features 4 density 5 streak 6 luster 7 cleavage or fracture 8 color. (to find out hardness look up "Mohs scale of hardness" everything else you could search it on google or bing)
Dose sapphire have a cleavage break or a fracture?
Sapphire has a mixture of both cleavage and fracture characteristics. It has poor cleavage in one direction and conchoidal fracture, which means it breaks with smooth, curved surfaces similar to glass.
Does fluorite have cleavage or fracture?
It has both: uneven fracture, and perfect cleavage in three directions.
Does feldspar have cleavage?
It has both cleavage and fracture.
