ʻO ka pauka Barite (Precipitated barium sulfate), i ʻike ʻia hoʻi he pauka barium sulfate, he ʻano kemika ʻo BaSO4, a ʻo kona kristal no ka ʻōnaehana orthorhombic (rhombic) o nā minelala sulfate. ʻO ka maʻamau, he ʻano mānoanoa a he kristal kolamu paha, ʻo ka hapa nui he poloka paʻa a he ʻano papa paha, he hui granular. Ke maʻemaʻe, ʻaʻohe ona kala a moakaka. Ke loaʻa nā mea haumia, ua hoʻoluʻu ʻia i nā kala like ʻole. He keʻokeʻo nā kaha a he ʻālohilohi ke aniani. He moakaka a hiki i ka translucent. ʻO ke kaumaha kikoʻī 3.5-4.5.
