The quality of white fused alumina can be assessed through two stages: an initial evaluation and a more comprehensive confirmation. Each stage focuses on key performance indicators that directly affect its industrial applications.
Initial Quality Assessment
A simple way to begin evaluating white fused alumina is by checking its aluminum oxide content. High-quality products typically contain a higher level of alumina, which ensures strong grinding and polishing performance. If the alumina content is low, the material should generally be rejected, as it indicates poor production quality.
Next, purity should be examined. White fused alumina with low purity is not acceptable, as impurities can negatively impact grinding efficiency and overall performance.
Hardness is another important factor in the initial assessment. If the hardness of white fused alumina is insufficient, its grinding capability will be weak, resulting in poor finishing quality and unstable processing results.
Final Quality Confirmation
Once the basic indicators are confirmed, wear resistance should be evaluated. High-quality white fused alumina offers excellent wear resistance and generates less dust during use. This makes it suitable not only for sandblasting applications with strict requirements on iron contamination, but also helps reduce dust exposure for operators in practical use.
Corrosion resistance is also an important consideration. Good corrosion resistance allows white fused alumina to perform reliably in a wider range of working environments.
Finally, if the material is intended for refractory applications, its refractoriness must be tested. Strong heat resistance ensures stable performance under high-temperature conditions, making it suitable for refractory material production.
