    Pauda Borona

    ʻO Boron, he mea kemika me ka hōʻailona B a me ka helu atomika 5, he pauda amorphous paʻa paʻa ʻeleʻele/ʻeleʻele. ʻOi loa ka reactive a hiki ke hoʻoheheʻe ʻia i loko o ka nitric a me ka sulfuric acid akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona a me ka etera. Loaʻa iā ia kahi kiʻekiʻe neutro absorption.
    Kūleʻa ʻo UrbanMines i ka hana ʻana i ka pauka Boron maʻemaʻe kiʻekiʻe me ka liʻiliʻi liʻiliʻi loa. ʻO ka nui o kā mākou pauka pauka maʻamau ma ka laulā o - 300 mesh, 1 microns a me 50 ~ 80nm. Hiki iā mākou ke hāʻawi i nā mea he nui i ka laulā nanoscale. Loaʻa nā ʻano ʻē aʻe ma ke noi.
