브라운 용융 알루미나는 소성 보크사이트를 고온(약 2000도 섭씨)의 전기 아크로에서 점진적인 용융 환원을 통해 제조된 제품입니다. 화학 조성은 주로 Al 2 O 3 (94.5-97%)과 잔류량의 TiO 2 , SiO 2 , Fe 2 O 3 , CaO 및 MgO로 구성됩니다.
브라운 알루미늄 산화물은 좋은 인성, 높은 기계적 저항성 및 경도(모스 척도 9)가 특징입니다. 재료의 미소경도는 약 1900kG/mm 2 에 이릅니다 . 비중(밀도)은 3.90+/-0.05 g/cm 3 입니다 . 크기에 따른 벌크 밀도는 1.52-1.87 g/cm 3 입니다 . 비교적 높은 열전도도와 낮은 열팽창을 가지고 있습니다. 전기에 관해서는 절연체입니다.
