Spinell-Pulver ( Magnesium Alumina Spinel powder, PR982623, OV)

Description du marché

High‐purity powder is required to produce transparent spinel ceramics. Transparent ceramic materials offer superior mechanical, optical and chemical properties compared to common transparent materials such as glasses and polymers. Their extended transmission window up to the near infrared wavelength range makes the ceramics suitable for application in optical devices such as laser components, optical lenses and sensor systems. The fabrication of transparent ceramics is challenging. To provide optical transparency, pores and impurity phases must be avoided, i.e., very pure raw materials must be used. The chemical composition of the powder consists of Al2O3/MgO (summation formula MgAl2O4). A powder to produce transparent MgAl2O4 ceramic by means of common ceramic technology process must have appropriate properties in terms of Specific Surface Area, Particle Size d50, Si‐Impurity and Ratioo Al2O3/MgO.
