燒結性
英文
agglomerability-
Beryllium powders with the same particle size and various contents of beo were prepared by pre - sintering - acid washing processes initiatively and the influence of beo alone on o mys of beryllium was observed and some new results have been obtained - compared with the content of beo, the distribution of beo in beryllium has more critical influence on mys ; finely dispersed beo along the grain boundaries and in the matrix results in the dispersion strengthening of beryllium matrix and thereby the higher mys value ; on the contrary, the coarser beo particles clustering on the grain boundaries results in negative influence on o mys
開創性地用預燒結? ?酸洗工藝制備了相同粒度、不同beo含量的鈹粉,從而開展了beo含量單獨對鈹材_ ( mys )影響的研究,得出一些新的結果:與beo含量相比, beo在鈹中的分佈狀態對_ ( mys )的影響更大。沿晶界、晶內彌散分佈的較細小beo對基體鈹有彌散強化作用,使_ ( mys )即較高;如果beo較粗大地成簇狀聚集在晶界,反而對_ ( mys )有不良的影響。( 2 ) the properties of the material with finer andalusite particle size are superior to those of coarse particle size at lower temperature, but properties of material of fine and coarse particle size have little difference at higher temperature. this illustrates that the andalusite particle size can lower the sintering temperature and that it brings forth not remarkable influence on the property of the material when the material is sintered completely
( 2 )對于不同粒度的原料,在燒成溫度較低的情況下,粒度小的材料性能明顯高於粒度大的材料,但在燒成溫度較高的情況下,兩者差別不大,說明原料粒度減小能降低製品的燒結溫度,但在制品均完全燒結的情況下對材料性能影響不大。Lifepo4 was sintered by solid - state method, we found that the capacity of the sample which was synthesized by codeposition method exhibited high specific capacity ( 142 mah ? g - 1 ) and good cycling performance

研究者所關注的問題是選擇新的體系進行研究,以期得到性能更好的鋰離子導體材料,這也正是本論文的基本出發點;復合離子導體中第二相的加入改善了基質的界面結構和導電機制,不僅可以提高基質材料的電導率,還可以在一定程度上改善材料的其它性能,如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向;合成鋰離子導體,特別是成分復雜的體系以傳統的固相合成法為主,但這種方法需要較高的溫度,容易引起鋰的揮發,從而造成產物組成的偏移,而且不易得到顯微結構均勻的材料。Experimental research on sintering performances of imported powder iron ores with high and medium ignition loss
