What is the product born out of stringent demands?
Purity, thermal stability and traceability are the production principles brought by a white corundum manufacturer.
01
As a qualified manufacturer of high-quality raw materials for the medical field, we are deeply aware of the rigorous nature of this industry. Therefore, when addressing the key concerns of medical clients regarding leached impurities, biocompatibility, and ultrafine dust, we prioritize white corundum's dense α structure and low soluble impurities during production, making it suitable for polishing and grinding with stringent cleanliness requirements.
We provide comprehensive supporting data, including XRF/ICP (trace metals), leaching/dissolution testing, PSD (controlling the proportion of ultrafine particles <1µm), SEM surface morphology, and dust and respirable particle testing (mg/m³), to ensure customer satisfaction. Because white corundum offers significant performance advantages over common minerals or low-purity aluminum oxide, such as reduced metal ion migration, reduced surface contamination, and shortened validation cycles, we also offer customized services, including clear cleanliness levels, batch dissolution reports, and recommended process parameters.
02
The advantages of white fused alumina lie in its high purity (≥99% Al₂O₃ content), dense α phase, and low impurities. These properties directly influence the formation of low-melting phases, chemical attack, and thermal shock resistance in refractory systems.
In addition, we always provide customized services and data verification to meet customer needs. We offer various tests and data reports, including XRF/ICP (Al₂O₃%, Fe/Ca/Na limits), XRD (α phase confirmation), particle size/screening, TGA/DSC (thermal decomposition/phase transformation), thermal shock cycling, and HMOR/RUL flexural/compressive data. Furthermore, our high-quality white aluminum oxide is superior to industrial alumina powder and natural aggregates due to its lower impurities and better phase stability.
03
The tile and glass industries are particularly demanding of low impurities. To prevent glaze staining, strict particle size control is required to achieve a stable, high-quality surface gloss and low scratch rate. We provide on-demand data reports and customized services to ensure customer satisfaction. These services include XRF/ICP (soluble salt/trace iron and chromium content), PSD (narrow distribution), before-and-after polishing comparisons, micro-scratch depth testing, TGA/DSC (thermal stability), and surface coloration testing, among other customized data tests.
White corundum, unlike other raw materials, exhibits superior high-temperature resistance and low impurities. Especially compared to super-hard abrasives like SiC, white corundum offers advantages in avoiding chemical reactions on glazes and the risk of color shift. This makes it highly sought after in the raw material market.
