Ama-microsphere engilazi, aziwa nangokuthi ama-Hollow Glass Microspheres (HGM), awuhlobo lwezinto ezicutshungulwe ngokukhethekile ezilula, ezingezona ezensimbi, nezinemisebenzi eminingi. Akhiwe ngokuyinhloko nge-borosilicate futhi akhiqizwa ngokushisa okuphezulu emazingeni okushisa asukela ku-700 kuya ku-800℃. Njengoba enobukhulu bezinhlayiya ngokuvamile buphakathi kwama-micrometer ayi-10 nama-250 kanye nobukhulu bodonga obungama-micrometer ayi-12, la ma-microsphere anobukhulu be-micron futhi abonisa izakhiwo ezinhle kakhulu njengokukhanya, amandla aphezulu, ukuvikela ukushisa, kanye nokumelana nokugqwala.

Ama-microsphere engilazi anezindlela eziningi zokusetshenziswa ngenxa yezakhiwo zawo ezihlukile. Avame ukusetshenziswa njengezigcwalisi ezintweni ezifana ne-fiberglass, lapho anganciphisa khona isisindo, athuthukise ukuqina, amandla okushaya, kanye namandla okugoba, kuyilapho futhi ethuthukisa ukuzinza kwamakhemikhali kanye nokucutshungulwa kabusha. Ngaphezu kwalokho, angathatha indawo yezingxenye ze-resin ezibizayo, ehlisa izindleko zokukhiqiza. Ezintweni ezihlanganisiwe zokulungisa, njenge-putty, anikeza ukunamathela okulula, okuqinile, ukusetshenziswa okulula, ukuncishiswa okuphansi, kanye nokuzinza okuhle.

Sekukonke, ama-microsphere engilazi ayizinto ezisebenziseka kalula futhi eziwusizo ezinekhono elikhulu lokuthuthukiswa nokusetshenziswa okuqhubekayo ezimbonini ezahlukahlukene.
