Ubunzima obuKhanyayo beSitena sokugquma iSilica yamkela i-silica ore eyahlulwe kakuhle njengemathiriyeli ekrwada. ubungakanani beqhekeza elibalulekileyo alikho ngaphezu kwe-1mm, apho ngaphezu kwe-90% ubungakanani be-particle bungaphantsi kwe-0.5mm. Isitena sokufakelwa kwe-silicate senziwe ngokongeza into enokutsha kumthwalo okanye ukwamkela indlela ye-bubble yerhasi ukuvelisa ubume be-porous ngokudubula, izitena zokugquma i-silicate nazo zingenziwa ukuba zibe yimveliso engatshiyo.
Light Weight Silica Insulation Brick ibeka imathiriyeli ekrwada kunye namanzi kwisixhobo sokuxova ngokomlinganiselo othile kwaye emva koko ixutywe eludakeni, imise udaka lube zizitena ngokubunjwa ngoomatshini okanye abasebenzi. uze womise izitena kuze kube yilapho umthamo wamanzi oseleyo ungaphantsi kwe-0.5%, okuthintela ukwandiswa kwevolumu ukusuka kwi-crystal transformation ye-SiO2 kunye nomlilo izitena ezibunjiweyo kwiqondo lokushisa eliphezulu.

I-silica insulation refractory isitena sinokusetyenziswa kwiziko leglasi kunye nesitovu esitshisayo, ibhlokhi yokugquma i-silica nayo ingasetyenziswa kwii-oveni ze-coke, iziko lokwenziwa kwekhabhoni kunye nazo naziphi na ezinye iziko loshishino.
