BORON PWDER
Boron, kahi Element Element me ka hōʻailona b a me ka helu atomic 5, he mea nui a me kaʻeleʻele He mea nui loa ia a lūlū i loko o nā lāʻau nitric a me nā maʻi sulfuric a me nā mea momona i loko o ka wai, ka waiʻona a me ka eter. He nui ka nui o ka hiki i ke komoʻana o Neutro kiʻekiʻe.
Nā mea hoʻohālikelike o nā kūlanakauhale i ka hanaʻana i ka nui o ka powder ka nui o Boron me nā liʻiliʻi liʻiliʻi o ka nui. ʻO kā mākou mau papa hana maʻamau i ka nui o ka nui o ka nui o ka palena o - 300 mesh, 1 microns a me 50 ~ 80nm. Hiki iā mākou ke hāʻawi i nā mea he nui i loko o nā wahi o ka nanoscale. Loaʻa nāʻano'ē aʻe i nā noi.
