Alkali- and CO-resistance of dense calcium hexaluminate Bonite

Abstract

Calcium hexaluminate Bonite was introduced as a new synthetic dense refractory aggregate in 2004. Key material properties are high chemical purity, high refractoriness, high thermal shock resistance, and high resistance to corrosion by molten aluminium. For the current paper further tests with Bonite based castables have been performed, such as alkali-resistance, CO-resistance, and thermal conductivity focusing especially on applications in cement-, glass-, and petrochemical industries.
