Fused silica is a popular choice of melting vessel material due to excellent thermal and chemical stability, allowing vessels to be used with a wide range of materials that may be subject to rapid temperature changes during processing.
However, some manufacturing methods can lead to inconsistent vessels, which risk a much-reduced lifetime, or even failure, during the melting process.
To overcome these shortcomings, high-purity fused silica melting vessels from Goodfellow are moulded, producing optimal characteristics for demanding melting applications.
High-purity moulded fused silica melting vessels from Goodfellow.
- Specific features of high-purity moulded fused silica melting vessels include:
- Seamless one-piece construction of fully dense material
- Uniform microstructure with isotropic properties
- Nonporous, unreactive internal surface for easy removal of melted material
- High-purity fused silica to minimize the possibility of product contamination
- Long lifetime of the melting vessel.
Goodfellow offers high-purity moulded fused silica melting vessels in a wide range of sizes, capacities and shapes – including square, cylindrical and rectangular. Custom sizes can also be produced, with current maximum sizes having an outer diameter of 635mm and a height of 400mm.
