According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
apatite will not scratch quartz topaz calcite or corundum
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
I would guarantee that diamond would scratch it, and types of corundum like rubies, sapphires and raw corundum probably would, because it is 9 on the moh's scale of hardness. Quartz, emerald, agate and topaz would also scratch it.
The mineral that can scratch glass but can be scratched by a steel file is quartz. Quartz has a hardness of 7 on the Mohs scale, allowing it to scratch glass, which typically has a hardness of around 5.5. However, a steel file, which has a hardness of about 6.5 to 7, can scratch quartz.
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
apatite will not scratch quartz topaz calcite or corundum
Anything under the 7 of the Moh's Hardness Scale, which is the number assigned to quartz. Minerals that can scratch quartz include topaz, corundum and diamond - pretty much everything else won't scratch it.
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
It can be scratched by a diamond, corundum, topaz, and quartz.
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
Fluorite is a relatively soft mineral with a Mohs hardness of 4, so it can be scratched by harder materials like quartz, topaz, and corundum. However, fluorite can scratch materials with a lower hardness, such as gypsum and calcite.
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
Quartz is the mineral that can scratch glass and be scratched by topaz. Quartz ranks 7 on the Mohs scale of mineral hardness, scratching glass which ranks around 5.5. Topaz, ranking 8 on the Mohs scale, can scratch quartz but not glass.
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
