Brown Fused Alumina (BFA) is a highly used abrasive material. It is manufactured by fusing calcined bauxite in a reducing atmosphere. It is preferred in various industrial processes for surface preparation, polishing, grinding, and multiple refractory operations.The better the quality of this brown fused alumina content is of utmost importance as it is directly related to the performance in various applications. So, if you don’t want to invest in unreliable quality solutions, stay tuned. This quick post explores some critical and proven methods to test the quality of brown fused alumina.
The top quality brown fused alumina will have a higher content level of alumina. It showcases better strength and operational efficiency. You should ensure that there are minimal impurities involved i.e., silica, titanium oxide, etc. Additionally, laboratories often prefer X-ray fluorescence (XRF) to assess chemical composition of the fused brown alumina solutions.
For distinguished industrial applications, you need to understand that different grain sizes of the brown fused alumina powder are suggested. So, you should ensure that the test of particle size distribution through sieve analysis or laser diffraction is effectively conducted.
To ensure a strong, high-density product, you need to understand the bulk density measuring. With consistent density, you can be sure about the brown fused alumina to be able to perform uniformly for different industrial operations.
The Mohs hardness scale and microhardness tests are preferred to make sure that the brown fused alumina refractory material has a rating of approximately 9. This rating reflects the toughness and hardness of the solutions, making them suitable for durability and long-lasting performance.
Excessive iron material or magnetic impurities is not a good sign for brown fused alumina content. It will negatively impact the overall performance of this BFA material for both abrasive and refractory applications. With the help of a magnetic separator or tester, it becomes convenient to identify and eliminate the contaminations.
If you want your industrial applications to run smoothly and achieve better efficiency, quality testing of BFA is a must. You can use these methods we discussed above and ensure making the right decision of brown fused alumina for your industrial needs.
