| 简介 |
Process for the production of a material based on α-SiAlON (R x Si12 - (m + n) Alm + n O nN8-n with 0 < n ≤ 2, 0.3 ≤ m < 2, x = m/3 and R selected from the group Li, mg, Ca, rare earth metals or mixtures thereof) and β-SiAlON (Si 6-8-z Oz z ≤ 4.2 z Alz N with), wherein a powder mixture, which contains a component selected from the group Si 3 N4, 3 2 O Al, AlN, or mixtures thereof, together with a compound of metals R β-SiAlON pre-alloyed is prepared and then at temperatures above 1450 °C is compacted. |
