Method for evaluating suitability of silica powder for manufacturing of silica-glass crucible for pulling silicon single crystal |
| abstract |
An evaluation method of suitable silica powder for forming a bubble-free layer of a vitreous silica crucible for pulling of a silicon single crystal, includes: a process of measuring a porosity between silica particles in the silica powder, a process of melting the silica powder, a process of measuring a bubble content rate of a vitreous silica block obtained by cooling to harden the melted silica powder, and a process of determining whether the silica powder is suitable from the porosity of the silica powder and the bubble content rate of the vitreous silica block. |
