Abstract
A high-density mullite which can be used as an oxygen sensor at high t emperatures, did not show enough thermal shock fracture resistance in the melts of steel. The thermal stress distribution in a mullite tube after immersing into steel melts was calculated by the finite element method in order to prevent thermal spalling. Based on the calculated r esults, the resin-coated mullite tubes and the porous mullite tubes wi th excellent thermal shock fracture resistance were developed.
