| 发明名称 | Glass preform manufacturing method | ||
| 摘要 | A glass preform manufacturing method, includes: preparing a glass element having a rough surface; turning a raw material of an alkali metal compound or a raw material of an alkaline earth metal compound into particles; depositing particles of the alkali metal compound or the alkaline earth metal compound on the rough surface of the glass element; oxidizing the particles of the alkali metal compound or the alkaline earth metal compound while diffusing alkali metal oxide or alkaline earth metal oxide in the glass element; and manufacturing a glass preform into which the alkali metal oxide or the alkaline earth metal oxide is doped. | ||

| 主权项 | 1. A glass preform manufacturing method, comprising: preparing a glass element having a rough surface; heating a raw material of an alkali metal compound or a raw material of an alkaline earth metal compound, generating vapor of the alkali metal compound or the alkaline earth metal compound causing the vapor to flow into a cooling portion, cooling and condensing the vapor, thereby generating particles at the cooling portion; depositing particles of the alkali metal compound or the alkaline earth metal compound on the rough surface of the glass element; oxidizing the particles of the alkali metal compound or the alkaline earth metal compound while diffusing alkali metal oxide or alkaline earth metal oxide in the glass element; and manufacturing a glass preform into which the alkali metal oxide or the alkaline earth metal oxide is doped. | ||
