Ka hoʻohana ʻana i ka cerium carbonate
ʻO ka cerium carbonate 99.99% rare earth, ua hoʻohana nui ʻia i ka hana ʻana i ka catalyst auto a me ke aniani, a ma ke ʻano he kumu kumu no ka hana ʻana i nā pūhui Cerium ʻē aʻe. I loko o ka ʻoihana aniani, ua manaʻo ʻia ʻo ia ka mea ʻoi aku ka maikaʻi o ke aniani polishing agent no ka precision optical polishing. Hoʻohana ʻia nō hoʻi e decolorize i ke aniani ma ka mālama ʻana i ka hao i kona kūlana ferrous. Hoʻohana ʻia ka hiki o ke aniani Cerium-doped e ālai i ke kukui ultra violet i ka hana ʻana i nā kīʻaha lāʻau lapaʻau a me nā puka makani aerospace.
