Isku-darka laba-geesoodka ah ee faakuumka ilkaha ee Maxwell 10 litir oo leh dahaarka tungsten trioxide (WO3) ayaa loo habeeyey sida uu macmiilku u codsaday. Waxay ku habboon tahay soo saarista dufcado yaryar oo leh viscosity sare marar badan. Baaldiyada walaaqaya ee Tungsten oxide-ka lagu dahaadhay waxay bixiyaan iska caabin sare oo xirasho ah, iska caabin daxaleed, sifooyin aan dhegdheg lahayn, iyo hawlgal aan wasakhayn, taasoo ka dhigaysa kuwo aad ugu habboon ilkaha iyo agabka kale ee nadaafadda sare leh. Waxay hubiyaan habka isku-darka saafiga ah waxayna xoojiyaan cimri dhererka qalabka. Isku-darkani si isku mid ah ayuu ugu habboon yahay isku-darka agabka leh shuruudaha wax-soo-saarka ee si siman u baahan.
Noocyo badan oo dahaadh ah ayaa la heli karaa, sida tungsten oxide, zirconium oxide, PTFE (Teflon), iwm. Waxaan dahaarka u habeyn doonnaa iyadoo lagu saleynayo habka wax soo saarka macaamiisha iyo agabka.
Waxay ku habboon tahay kala firdhinta iyo isku darka walxaha ku jira dareeraha viscosity-ga sare, sida e-dhegaha injineernimada, tamar cusub, koollada slurry-ga korontada ku shaqeeya, koollada kiimikada. Dhammaan noocyada koollada leh viscosity sare, waxyaabaha adag ee ka hooseeya 90%, sida koollada baytariga lithium, koollada alxanka, koollada dhoobada, khad silikoon ah, shaabadayn, koollo qaab-dhismeed, boomaato, walxaha buuxinta isku dhafan, walxaha isbeddelka marxaladda, koollada ilkaha, iwm.
