Comparation of garnet sand and low quality brown fused alumina as anti-slip material
Because garnet sand and brown fused alumina are both high hardness,good strength and toughness,wear resistant,corrosion resistant and high temperature resistant etc,they are used as anti-slip material in coating field.
Then what are the differences between them?
1.Appearance
Garnet sand | Brown fused alumina |
2.Main chemical compostion
Item | Garnet sand | brown fused alumina |
Al2O3 | 17-21% | 40-60% |
SiO2 | 34-40% | 12-15% |
Fe2O3 | 25-31 | 15-20% |
3.Main physical properties
Item | Garnet sand | Brown fused alumina |
Bulk Density | 1.8-1.9g/cm3 | 1.53-1.99g/cm3 |
Specific Gravity | 3.8-4.1g/cm3 | ≥3.90g/cm3 |
Mohs Hardness | 7.5-8.0 | 8.0-9.0 |
Melting Point | 1300℃ | 2250℃ |
4.Cost
The quality of brown fused alumina has almost the same cost with garnet sand,then more and more users use garnet sand or brown fused alumina as anti-slip material.
