Brown Fused Alumina Oxide Manufacturers Brazil

About 15% of the abrasive is a 120 grit aluminum oxide harbor freight crystalline aggregate that is bound together by a certain amount of glass glue. Most of the silica in 220 grit aluminum oxide blast media is found in the glass phase. The shape of the sand grains is more acute-angled needles, the bulk density is relatively low, and the particle size distribution is more concentrated.

This glass contains various mineral components such as anorthite, titanium dioxide, etc. Nearly 5% of the abrasive particles are crystalline aggregates of brown fused alumina and calcium hexametaluminate or calcium calcium plagioclase, 80 grit aluminum oxide blasting media particles with titanium non-oxide and iron alloy impregnated bodies, and some even It is a piece of glass containing various mineral components, so-called slag.(brown fused alumina oxide manufacturers brazil)

If there is excess titanium oxide (TiO2) in white alumina, it cannot remain in the glass phase, but reacts with alumina to form aluminum titanate (TiO2 (Al2O3)). Aluminum titanate is the third phase at the interface between α-alumina grains and glass phase, 100 grit aluminum oxide media which will weaken the glass phase between α-alumina grains. The difference in thermal expansion coefficient between the three phases also causes cracks between the grains during heating.

(brown fused alumina oxide manufacturers brazil)The typical TiO2: SiO2 ratio of typical brown aluminum oxide is 2.5: 1 to 6: 1. Most of titanium dioxide exists as a solid solution of α-alumina grains. During the reduction process in the furnace, a part of TiO2 is reduced to a titanium oxide (Ti2O3). Attention must be paid to the proportions of the titanium dioxide and the alumina fused mixture to maintain the technically qualified 1200 grit aluminum oxide.

At the same time, TiO2 in black corundum cannot be over-reduced. The amount of Ti2O3 dissolved is very important for the calcined color and toughness of 46 grit aluminum oxide. The particle size of the P particle size starts with the English letter "P", plus Arabic numerals. The larger the value, the finer the particle size of the abrasive. The granularity labels are: p240, p280, p320, p360, p400, p500, p600, p800, p1000, p1200, p1500, p2000, p2500.(brown fused alumina oxide manufacturers brazil)

brown aluminium oxide P sand is processed on the basis of brown corundum F sand standard through further screening and washing processes. This aluminum oxide blast media 60 grit P sand does not undergo high temperature calcination, its shape is pointed, its grinding ability is high, and its self-sharpening is good. When this reaction occurs, the volume of titanium sulfide increases significantly, and the specific gravity decreases accordingly. 

(brown fused alumina oxide manufacturers brazil)pink corundum P sand is mainly used for coating abrasives. When brown corundum is heated in contact with air, the titanium sulfide impurities in brown corundum are transformed into rutile. When the contact temperature of brown corundum reaches 900 degrees Celsius, titanium sulfide will transform into rutile, which is one of the reasons for the abnormal thermal expansion of brown fused alumina manufacturer in the range of 900 degrees Celsius.
