Enwere ike iji zirconia kwụsiri ike nke Magnesia na valvụ, nfuli, na gaskets n'ihi na ọ nwere oke iyi na nguzogide corrosion. Ọ bụkwa ihe kachasị amasị maka ngalaba nhazi petrochemical na kemịkalụ. Zirconia ceramics bụ nnukwu nhọrọ maka ọtụtụ ngalaba, gụnyere:

• Seramiki ihe owuwu

• Nri

• Yiri akụkụ

• Yiri uwe aka

• fesa nozzles

• Pump aka uwe

• fesa pistons

• Bushings

• Akụkụ mkpụrụ ndụ mmanụ oxide siri ike

• Ngwa MWD

• Ntuziaka Roller maka ịkpụ tube

• Nke ọma miri emi, downhole akụkụ
