国家将原标准的部分指标进行了调整，对微硅粉的杂质含量也进行了严格的控制，具体对钙镁、钾钠和灼碱指标进行的调整，更有利于微硅粉PH值的控制，比表面积也统一为了≥15㎡/g，具体标准如下：
| 项目 | 指标 | 规格 | |||
| SF96 | SF93 | SF90 | SF88 | ||
| SiO2 | ≥ | 96% | 93% | 90% | 88% |
| AL2O3 | ≤ | 1.0% | 1.0% | 1.5% | — |
| Fe2O3 | ≤ | 1.0% | 1.0% | 2.0% | — |
| CaO+MgO | ≤ | 1.0% | 1.5% | 2.0% | — |
| K2O+Na2O | ≤ | 1.0% | 1.5% | 2.0% | — |
| C | ≤ | 1.0% | 2.0% | 2.0% | 2.5% |
| 灼碱 | ≤ | 1.0% | 3.0% | 3.0% | 4.0% |
| 水份 | ≤ | 1.0% | 2.0% | 2.5% | 3.0% |
| 粒度（45μm筛余） | ≤ | 3.0 | 3.0 | 5.0 | 8.0 |
| 比表面积㎡/g | ≥ | 15 | |||
| PH值 | = | 4.5~6.5 | 4.5~7.5 | 4.5~7.5 | 4.5~8.5 |
