Libolo tsa letsopa li nkiloe ho tsoa phofong e tsoetseng pele ea letsopa e kang alumina (Al₂O₃), zirconia (ZrO₂), silicon nitride (Si₃N₄), le silicon carbide (SiC). Lisebelisoa tsena tse tala, tse fumanoang e le likaroloana tse ntle haholo, li feta lits'ebetsong tsa metallurgy ea phofo: li kopantsoe le li-binder, li etsoa li-preform tse chitja ka ho hatella ka isostatic kapa ho enta ka ente. Li-preform li ntan'o sintered ho 1,400–2,200°C ho etsa meaho e teteaneng, e ts'oanang. Kamora ho sila, ho sila ka nepo le ho bentša li ntlafatsa ho fihlela maemong a micron.

Libolo tsa letsopa li fana ka lits'ebetso tse fapaneng ka lebaka la ho ba thata haholo le ho hanyetsa mafome. Li-bearing, li fokotsa khohlano mechineng e lebelo le phahameng joalo ka likoloi tsa motlakase le li-drill tsa meno, e leng se eketsang katleho. Bakeng sa li-valve le lipompo, thepa e kang silicon nitride e mamella lik'hemik'hale tse matla indastering ea oli le ea meriana, e leng se netefatsang hore e phela nako e telele. Tlhahisong ea li-semiconductor, libolo tsa letsopa tse sa tsamaiseng motlakase li hloekisa likarolo tse bonolo ntle le tšilafalo. Li boetse li sebetsa e le mecha ea ho lahla ka mokhoa o nepahetseng bakeng sa likarolo tsa lifofane kapa mabenyane, e leng se fanang ka qetello e boreleli.
