The influence of nano - al2o3 on the sintering and the properties of the si3n4 ceramics was researched in this paper. the samples with different amount of nano - al2o3 were obtained by using pressureless sintering at 1600, 1650, 1700 in the nitrogen atmosphere. the microstructure and the composition of the ceramics were determined by the means of x - ray, sem, micro - hardness meter etc. it is show that the sisty ceramics can be densified at 1650c to % percent of the theory density through the addition of nano - al2o3 ( the value could be 90 percent by other technique ). the crystalline growth of the cylindrical - si3n4 and the ratio of its longitude to its diameter are increased with the addition of nano - al2o3. a uniform microstructure and an fined crystal as well as more sialon phases can be obtained in the si3n4 ceramics through the addition of that
實驗結果表明：在碳管爐中、氮氣保護下進行燒結，添加劑為納米al _ 2o _ 3粉末時，由於納米粉末的高活性、高燒結驅動力，在1650就可使si _ 3n _ 4完全地燒結，並使其緻密度可達理論密度的96以上（比其它工藝高6左右） ；同時，納米al _ 2o _ 3地加入大大促進了長柱狀? si _ 3n _ 4的生長和發育及柱狀晶長徑比的提高，使微觀結構均勻、細化，形成了更多力學性能優異的固體? sialon相，減少了不利於陶瓷材料性能的晶間玻璃相，凈化了晶界。 -
The objective of this paper is to obtain metal - ceramic composite materials with better complex properties by the way of preparing nano - composite powders of metal and ceramic. in our thought, firstly we should prepare nano - ceramic powders coated with metal, and then during the period of sintering, the film of metal could prevent the nano ceramics powder from dumpling and keep the powders to be nano - sized
這樣，在隨后制備塊材的燒結過程中，由於復合粉體復合充分，相容性提高，結合力高，另外金屬表面層可抑制納米陶瓷粉體的融合長大，使粉體在燒結后保持納米尺寸，從而發揮納米顆粒的作用；同時通過引入均勻分佈的韌性金屬相，進一步改善陶瓷的脆性。 -
