 The
fused materials branch plant has cooperated with the
High Temperature Material Research Institute of Zhengzhou
University to produce fused raw materials such as zirconia
composite periclase,spinel, bauxite-based M-A spinel,
bauxite-based mullite, brown corundum bubble,etc. Tested
by the National Quality Supervision and Inspection Center
on Refractories and Zhengzhou Research Institute of
Abrasive Tool and Abrisive Materials , the products
were found sound quality, especially the bauxite-based
magnesia-alumina spinel, whose chemical and physical
properties have reached to an advanced level and is
a high grade refractories material for ladle to replace
the high purity alumina-magnesia spinel. |
