Chemical Composition and Analysis
All analyses were conducted following Indian Standards (IS) and international testing protocols. The results are summarized below:
| Parameter | Result (%) | Industrial Significance |
|---|---|---|
| Phosphorus (P₂O₅) | 0.003% | Extremely low phosphorus prevents bubble formation during glass melting. |
| Silica (SiO₂) | 99.8% | High purity silica ensures thermal stability, hardness, and low expansion. |
| Ferric Oxide (Fe₂O₃) | 0.04% | Maintains brightness and clarity in glass and ceramics. |
| Alumina (Al₂O₃) | 0.03% | Improves transparency and lowers melting point. |
| Sodium Oxide (Na₂O) | 0.006% | Acts as mild flux while keeping EC controlled. |
| Potassium Oxide (K₂O) | 0.003% | Stabilizes thermal expansion in high-temperature applications. |
| Loss on Ignition | 0.04% | Indicates minimal volatile impurities. |
| Sulphur (S) | 0.008% | Trace level with negligible industrial impact. |
| Bulk Density (g/L) | 1.7 | Improves strength and durability during melting. |
| Specific Gravity | 2.67 | Enhances thermal shock resistance. |
| Calcium Oxide (CaO) | 0.0172% | Ensures consistent particle packing. |
| Magnesium Oxide (MgO) | 0.001% | Supports mechanical strength and heat resistance. |
| Grain Size (12.5mm–10mm) | 100% | Uniform grain size ensures controlled melting. |
| Passing on 10mm | 0% | Reduces dust and improves handling. |
| Total Moisture | 0.12% | Prevents caking and ensures stable storage. |
| Electrical Conductivity (EC) | 3–5% | Suitable for ceramics, glassmaking, and foundry use. |
