Recently, partial phase diagram of yttrium aluminate and AfN was reported (40). The eutectic point of the AIN-Y4AI2O9 system was 1790°C, and the AfN-Y3Al50i2 system was as low as 1690°C, which indicated the liquid phase sintering of AIN (Fig. 21). 

In processes with conventional quench rates of 10 K/s, the inviscid liquid (melt) or resulting jet is carefully under- or supercooled to its narrow fiber forming range (log 2.5 to log 3.0 poise). Three types of fibers have been made by variants of this process continuous optical yttrium aluminum garnet (YAG) glass fibers, continuous aluminate glass fibers and steel fibers.
