Perlite

Perlite bụ iko mgbawa ugwu amorphous nke nwere oke mmiri dị elu, nke a na-etolite site na hydration nke obsidian. Ọ na-apụta n'ụzọ nkịtị ma nwee ihe a na-adịghị ahụkebe nke ịgbasa nke ukwuu mgbe ọkụ zuru oke. Ọ bụ ịnweta ụlọ ọrụ mmepụta ihe, kwesịrị ekwesị "dị ka seramiiki flux iji belata okpomọkụ nke sintering", yana ngwaahịa azụmahịa bara uru maka njupụta ya dị ala mgbe nhazi ya.

Perlite na-adị nro mgbe ọ ruru okpomọkụ nke 850-900  . Mmiri tọrọ n'ime ihe ahụ na-agbaze ma na-agbapụ, nke a na-eme ka ihe ahụ gbasaa ruo okpukpu 7-16 nke mbụ ya. Ihe gbasaa bụ ihe na-acha ọcha na-egbuke egbuke, n'ihi ngosipụta nke efere ndị a tọrọ atọ. Unxpanded ("raw") perlite nwere nnukwu njupụta gburugburu 1100 kg/m3 (1.1 g/cm3), ebe a na-ahụkarị perlite gbasaa nwere nnukwu njirimara nke ihe dị ka 3-150 kg/m3.
