Kūʻai kūʻai nui i ke one silica maloʻo maoli
ʻO ke one silica, ʻike ʻia hoʻi he silica a i ʻole ke one quartz.He ʻāpana refractory me ka quartz e like me ka ʻāpana mineral nui a me ka nui o ka nui o 0.020mm-3.350mm, i māhele ʻia i ke one silica artificial a me ke one silica maoli e like me ke one i holoi ʻia, ke one scrubbing, a me ke one koho (flotation) e like me. nā ʻano hana eli a me nā ʻano hana like ʻole.ʻO ke one silica kahi mineral silicate paʻa paʻa, paʻa i ke kino, ʻo kona ʻano mineral nui ʻo SiO2, ʻo ka waihoʻoluʻu o ke one silica he milky keʻokeʻo a i ʻole translucent kala ʻole, paʻakikī 7, brittleness me ka ʻole o ka cleavage, ʻāhaʻi like me ka shell, grease luster, pili. mānoanoa o 2.65, kona kemika, wela a me ka mechanical waiwai anisotropy maopopo, insoluble i loko o ka waika, iki iki i KOH solution, hehee wale 1750 °C.He keʻokeʻo waiu ka waihoʻoluʻu, melemele māmā, ʻeleʻele a hinahina, ʻo ke one silica ke kūpaʻa ahi kiʻekiʻe.
