The eutectic crystal al3fe often is " needle " shape or short line shape but the shape of primary crystal al3fe is relative to the adding amount of fe powder and the temperature of heat preservation stirring. while the adding amount of pure fe powder is few and the temperature of heat preservation stirring is higher than the temperature of liquidus of al - fe binary alloys equilibrium phase diagram, the reaction synthetical primary crystal al3fe exhibits short worm shape
加入量少，保溫攪拌溫度在al - fe二元合金液相線以上，則形成的初晶al _ 3fe呈短蠕蟲狀； fe加入量大，保溫溫度在液相線以上，初晶al _ 3fe以平面方式生長，復合材料中的初晶al _ 3fe呈塊狀或粒狀，尺寸較大（ 10 m以下） 。 -
Na2o - 8teo2 crystal is stable at temperatures below 330 and will decomposed into two crystalline phase including na2o4teo2 and teo2 at 340 or a higher temperature. the phase diagram of sodium tellurite is modified according to the results obtained. the transformation of na2o - 8teo2 into na2o4teo2 and teo2 includes two steps : na2o - 8teo2 is first transformed into an intermediate amorphous phase and then the intermediate amorphous phase crystallizes to form na2o - 4teo2 and teo2 - the intermediate amorphous phase formed during the transformation is amorphous powder
通過對nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變過程的研究發現，由nt _ 8晶相向nt _ 4和teo _ 2晶相的轉變包括兩個轉變過程，即由nt _ 8晶相向非晶中間相轉變的過程和由非晶中間相向nt _ 4和teo _ 2晶相轉變的過程，在轉變過程中出現的非晶中間相是一種非晶固態粉末。
