Lehlabathe la Ceramic bakeng sa setsi sa motheo se na le ts'ebetso e ntle ea ho sebelisa hape: litlhoko tse tlase tsa lisebelisoa tsa kalafo ea lehlabathe, tšebeliso e tlase ea matla le litšenyehelo tse tlase bakeng sa kalafo ea lehlabathe. Sekhahla sa ho khutlisa lehlabathe se fihlile ho 98%, se hlahisa litšila tse fokolang. Ka lebaka la ho se be teng ha binder, lehlabathe le tlatsitsoeng la foam le lahlehileng le na le sekhahla se phahameng sa ho hlaphoheloa le litšenyehelo tse tlase, tse fihlang ho 1.0-1.5kg / tonne ea tšebeliso ea lehlabathe ea li-castings.
Lilemong tsa morao tjena, likhoebo tse lahlehileng tsa ho akhela foam li anngoe ke lintlha tse ngata, e leng se bakileng sekhahla se tlase sa maemo a tlase sa ho phethoa. Har'a tsona, litšenyehelo tse phahameng tsa tlhahiso ea li-castings, tekanyo e phahameng ea sekoli le boleng bo tlaase li fetohile mathata a mararo likhoebong tse lahlehileng tsa ho lahlela foam Chaena. Mokhoa oa ho rarolla mathata ana le ho ntlafatsa ts'ebetso ea litšenyehelo tsa lihlahisoa tsa lihlahisoa esale pele e fetohile e 'ngoe ea mesebetsi e ka sehloohong ea lik'hamphani tsa foundry. Joalo ka ha bohle re tseba, khetho ea lehlabathe nakong ea ho lahla ke karolo ea bohlokoa ea ts'ebetso eohle. Hang ha lehlabathe le sa khethoa hantle, le tla ama boemo bohle. Ka hona, likhoebo tse lahlehileng tsa ho lahla foam li lokela ho etsa boiteko bo bongata ho khethoeng ha lehlabathe.
Ho ea ka lintlha tse amehang, lik'hamphani tse ngata tsa foundry li ntlafalitse khetho ea tsona ea lehlabathe, li hana lehlabathe la quartz la theko e tlaase kapa lehlabathe la forsterite, le ho sebelisa mofuta o mocha oa lehlabathe la ceramic ho ntlafatsa bothata ba ho lahla. Mofuta ona o mocha oa lehlabathe o na le melemo ea ho refractoriness e phahameng, mokelikeli o motle, ho phunyeha ha khase e phahameng le bongata bo lekanang le lehlabathe la quartz. E rarolla liphoso tsa tlhahiso ea lihlahisoa ho isa bohōleng bo itseng, 'me e amehile haholo ke indasteri ea machaba ea lihlahisoa. Mathata a mararo a maholo a litšenyehelo tsa ho lahlela, sekhahla se senyehileng le boleng ba likhoebo tse lahlehileng tsa ho lahla lekoeba li fokotsoe ka nepo, 'me lehlabathe la ceramic le lona le ratoa ke likhoebo tse ngata.

● High refractoriness (>1800°C),can be used for casting various materials. There is also no need to use different sand type according to material.
● Sekhahla se phahameng sa ho khutlisa chelete. Sekhahla sa ho khutlisa lehlabathe se fihlile ho 98%, se hlahisa litšila tse fokolang.
● Mokelikeli o babatsehang le bokhoni ba ho tlatsa ka lebaka la ho ba chitja.
● Katoloso e tlase ea Thermal le Thermal Conductivity. Litekanyo tsa ho lahla li nepahetse haholoanyane mme conductivity e tlase e fana ka ts'ebetso e ntle ea hlobo.
● Tšebeliso e tlaase ea bongata. Joalo ka ha lehlabathe la maiketsetso le le bobebe ho feta lehlabathe la ceramic le kopantsoeng (lehlabathe la bolo e ntšo), zircon le chromite, le ka fetoha habeli palo ea hlobo ka boima ba yuniti. E ka boela ea sebetsoa habonolo haholo, e boloka litšenyehelo tsa basebetsi le ho fetisetsa matla a motlakase.
● Phepelo e tsitsitseng. Bokhoni ba selemo ba 200,000 MT ho boloka phepelo e potlakileng le e tsitsitseng.
