Applications 
1)80-120M zircon sand is used in investment casting, the processing is called dipping 
2)It can enhance the shell`s thickness 
3)It is specialize used in inner layer being mixed with silica sol.

Advantage

1 Tiny, round, solid ball shape provides greater surface area for improved performance and dispersion in its application

2 High refractory rating, lower specific gravity rating, and higher service temperature produces greater yield

3 With lower bulk density, it offers better air permeability for better performance as a result of its overall physical characteristics

4 Lower thermal expansion rate and thermal conductivity produces better results in intense heat environments

5 Standard particle size within each grade is ideal for specific applications

6 Raw material is easily reclaimed multiple times by dry method

7 Physical characteristics produce a lower breakage rate during dry crushing

8 Ceramsite sand is a cost effective, single sand application; no need to mix with other sands

9 Ceramsite Sand is environmentally friendly, reducing pollution and reusing raw materials
