Marootada dhalaalinta naxaasta waxaa lagu soo saaraa iyadoo la isticmaalayo alaab cayriin oo saafi ah, oo lagu sifeeyay farsamooyin horumarsan sida cadaadiska isostatic iyo sintering heerkul sare ah. Tani waxay hubinaysaa in crucibles ay leeyihiin cufnaan sare iyo isku mid. Dusha sare waxa si gaar ah loogu daweeyaa si kor loogu qaado ka-hortagga oksaydhaynta iyo guryaha-daxalka, taas oo dheeraynaysa cimriga curiyaha.
Qalabyada dhalaalka naxaasta ah ayaa si weyn loogu isticmaalaa qalabyada dhalaalidda ee kala duwan, oo ay ku jiraan foornooyinka korantada iyo foornooyinka kicinta, oo ku habboon hababka heerkulka sare ee ku lug leh naxaasta iyo naxaasta. Waxay lagama maarmaan u yihiin warshadaha sida:
