Research from the University of Pretoria in South Africa has shown that by adding 1% titanium dioxide to a high quality magnesia carbon brick can demonstrably improve its mechanical and thermal-mechanical properties – a finding that could gain traction in the present wave of enthusiasm for better performing refractory products.

Adding small amounts of titanium dioxide (TiO2) to magnesia-chrome bricks can noticeably enhance the performance of these refractory lining materials, delegates at the 14th Unified International Technical Conference on Refractories (UNITECR) in Vienna, Austria, heard yesterday.

Delphin Mulange, a researcher at the University of Pretoria, South Africa, explained how TiO2 can be...
