Pilika Silika

ʻO nā pōhaku silica, e like me ka inoa e hōʻike nei, ʻo ka nui o ka SiO2 (ʻoi aku ka nui ma luna o 93%). ʻO ka hana wela kiʻekiʻe o nā pōhaku silica e hilinaʻi nui ʻia i ka maʻiʻo SiO2, ka ʻike haumia, ka hoʻohui ʻana o ka mineral a pēlā aku. ʻO ka maʻiʻo SiO2 kiʻekiʻe, ka refractoriness kiʻekiʻe o nā pōhaku silica. He tridymite, cristobalite, koena quartz, a me aniani. Hoʻopili ʻia nā waiwai piliki silica e pili ana i ka hoʻololi ʻana o SiO2 crystalline phase.

Nā hiʻohiʻona:
1.Low bulk density,
2.Low thermal conductivity,
3.High ike porosity,
4.Good thermal ha'alulu kū'ē,
5.Great kiʻekiʻe wela mechanical ikaika,
6.High wela paʻa leo loli,
7.Strong acid slag erosion kū'ē.
