Matapihi whatu rūpahu He matapihi tiaki whakaata taiaho Mohs Hard 9

Whakaahuatanga Poto:

Ko te matapihi whatu rupi he huānga whatu mahi teitei i ahu mai i te karaihe kotahi rupi hangai parakore (alpha-Al ₂O₃:Cr³ +), i hangaia mā te whakamahi i ngā tikanga tipu tioata matatau pēnei i te whakawhiti wera, te tikanga kume rānei. Hei matapihi whatu motuhake taumata hangarau, ehara i te mea he rite noa ki te karāhe whatu tuku iho ōna āhuatanga tuku mārama, engari he kaha miihini pai ake hoki, ā, he tino manawanui ki te taiao. Ko tēnei momo matapihi he mea hanga mā te whakamahi i te tukanga miihini whatu tino tika, me te mutunga mata tae atu ki te 5/1 (kara-keri), ā, ka taea te pani motuhake kia tutuki ai ngā hiahia o te tono. I raro i ngā āhuatanga uaua pēnei i te pēhanga teitei, te pāmahana teitei me ngā taiao waikura, ka whakaatuhia e ngā Matapihi rupi ngā painga mahi kore e taea te whakakapi, ā, he wāhanga whatu matua tino nui i roto i ngā taputapu ahumahi teitei, ngā taputapu pūtaiao me ngā pūnaha tirotiro motuhake.
