Keʻokeʻo iki a i ʻole melemele māmā, ʻono a ʻawaʻawa ka pauka me ka gravity kikoʻī o 6.1 a me ka refractive index 2.25. ʻAʻole hiki ke hoʻoheheʻe i ka wai, akā hiki ke hoʻoheheʻe i loko o ka waika hydrochloric a me ka waikawa nitric. Huli ia i ka hina a me ka ʻeleʻele ma 200 ℃ huli i ka melemele ma 450 ℃, a he maikaʻi kona deductibility.
