High Alumina Castable Refractoriness Refractory

2020511 The refractoriness of high aluminum castable is the primary condition to test whether castable is used in high temperature kiln Refractoriness is a basic test item of high aluminum castable and the index of refractoriness is also a necessary item of the physical and chemical index detection of high aluminum castable

01mm Calcined Bauxite Aggregate For Antiskid Surfacing

Calcined Bauxite for refractory material Such calcination of bauxite has the properties of high alumina low iron high hardness small thermal expansion coefficient high refractoriness and stable thermal chemical performance so it is the main raw material of producing alumina and artificial corundum refractory materials

The spatial dispersion of atrial refractoriness and atrial

The local dispersion of conduction and refractoriness has been considered essential for induction of atrial arrhythmias This study sought to determine whether a difference of refractoriness and vulnerability for induction of atrial fibrillation between trabeculated and smooth as well as high and low right atrium may contribute to initiation of atrial fibrillation in dogs
