Description:Experiments show that the alpha phase change to beta phase to stable structure when the temperature is above 1300 ℃.The type of additives had an influence on the alpha to beta phase transition of SI3N4, and the effect of Y2O3 on the phase transition was the most obvious. Alpha Silicon Nitride Powder ceramic belongs to the high temperature refractory compounds, without melting point, SI3N4 using temperature is generally not more than 1300 ° C. Other than hydrofluoric acid, silicon nitride will not be corroded by other general acids and bases.Storage Condition:Silicon Nitride Powder should be stored in sealed, avoid light, dry place. Room temperature storage is ok.SEM  :
