---CHARACTERISTICS---
|
- Calcined evenly at high temperature(>1500°C
),stable in mineralogical composition and production
quality.
- Mineralogical composition consists of mullite
crystals and amorphousSiQ2 glass
only, both having iow and uniform rate
of thermal expansion ,thus giving articles with
good thermal shock resistance.
- With no crystalline SiQ2,rough
surface and angularity of aggregate,the acticles
have good strengh.
- Having no active ions,the gelation characteristic
of slurries are consistent.
- Has hard particles,giving good abrasion resistance
in use and transportation with no proeness to dusting.
