Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
Have you ever heard of the Moh's scale? I believe quartz ranks 7 and diamond 10. If you can obtain topaz which is more common then Corundum and it leaves a streak on the mineral then the mineral is Quartz, but if the topaz or coundum is scratched then it is indeed a valuable diamond.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
The basic Moh's hardness scale consists of: 1. Talc (softest) 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Feldspar 7. Quartz 8. Topaz 9. Corundum 10. Diamond (hardest)
Topaz does not have a chemical formula, as it is a mineral and not an element. Topaz has the chemical formula of Al2SiO4(F,OH)2.
apatite will not scratch quartz topaz calcite or corundum
Yes. Corundum will scratch topaz and every other mineral with a hardness of 9 or lower on the Mohs hardness scale.
Topaz is a mineral that can scratch quartz due to its hardness of 8 on the Mohs scale, while corundum, with a hardness of 9, cannot be scratched by topaz. This places topaz in between quartz and corundum in terms of hardness, allowing it to effectively scratch quartz but not corundum.
Corundum and Diamond.
It can be scratched by a diamond, corundum, topaz, and quartz.
The unknown mineral would be topaz. Topaz lies between apatite and corundum on the Mohs scale, making it capable of scratching apatite and being scratched by corundum.
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.
feldspar, quartz, topaz, corundum, diamond.... Diamond will diffidently scratch glass its also made to cut glass if you get tech with it. (alyssamc6)
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
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.
There are many minerals with hardness above 5.5 but the standard ones are feldspar,quartz, topaz, corundum and diamond.
Three minerals that can scratch quartz are topaz, corundum, and diamond. Topaz has a hardness of 8 on the Mohs scale, while corundum, which includes sapphires and rubies, has a hardness of 9. Diamond, the hardest natural material, ranks 10 on the scale, making it capable of scratching all other minerals, including quartz, which has a hardness of 7.
