Alpha Calcined Alumina (40micron)
Alpha Calcined Alumina:
Phase Transformation: Alpha calcined alumina is a result of the calcination process that involves heating aluminum hydroxide or other aluminum compounds to a temperature range where they transform into the alpha phase of alumina (α-alumina). This phase transformation is associated with changes in crystalline structure and properties.
Properties: Alpha calcined alumina typically has higher hardness, greater abrasion resistance, and better thermal stability compared to other forms of alumina. It also possesses a higher density and is known for its refractory and abrasive properties.
Applications: This type of alumina is commonly used in refractories, ceramics, abrasive applications, and as a catalyst support due to its high thermal stability and mechanical strength.
