The best choice between our three spinel standard products strongly depends on your ceramic process.
| Standard Spinel products (Typical values) |
S15CR | S25CR | S30CR |
| Chemical Composition | MgAl2O4 | MgAl2O4 | MgAl2O4 |
| Crystalline phase (%) | ≥ 99% Spinel | ≥ 99% Spinel | ≥ 99% Spinel |
| Corundum | ≤ 0.5% | ≤ 0.5% | ≤ 0.5% |
| Periclase | ≤ 0.5% | ≤ 0.5% | ≤ 0.5% |
| Specific Surface Area (m²/g) BET | 14 – 17 | 21 – 24 | 25 – 28 |
| PSD d50 (µm) Laser diffraction Horiba LA950 |
0.4 – 0.6 | 0.2 – 0.3 | 0.15 – 0.3 |
The main characteristics of our Spinel products bring optimal transparency with a low scattering loss, without any coloration or defect (black or white spots), and high mechanical properties. Possibility to customize the Spinel chemical composition: Co, Mn, Fe doping, Al/Mg stoichiometry. Often used for armouring, ballistic, detection, luxury & catalysis applications, S15CR also suits for feedstocks and tape casting.
S15 CR, S25CR & S30CR are :
For a better easiness to use, the range can also be available in spray-dried and ready-to-press form.
