The Synthesize Cordierite are made from high quality raw materials, produced by wet process, calcining under high temperature . Due to its good thermal shock resistance ,thermal conductivity and low thermal expansion coefficient, This cordierite is an ideal raw material for kiln furniture refractory applications , honeycomb ceramics ,and other industries. The Synthesize Low-alumina Mullite is make from good natural mineral raw materials, produce by multi-stage homogenization process, calcining under high-temperature , it has special mullite-high silica glass complex microstructure, with excellent thermal expansion coefficient, good high temperature stability, etc. it is the most suitable aggregate for manufacturing of high-quality mullite cordierite kiln furniture. Widely used in kiln furniture manufacturing, precision casting, refractory bricks and other industries.
