The addition of y - zro2 improves the fracture toughness of pcd and the grinding ratio also increases with the y2o3 content increasing . the optimum comprehensive properties of pcd can be achieved as the y - zro2 powders contain 2mol % y2o3 . aluminum addition in si3n4 or si3n4 bond pcbn can prevent y - zro2 powders from forming the nontransformable tetragonal phase
在si _ 3n _ 4及si _ 3n _ 4中介结合的pcbn中加入适量的al作为烧结助剂，可以避免不可相变的t相zro _ 2形成，使应力诱导相变增韧高温高压烧结的氮化硅系陶瓷成为可能。
Piezoelectric properties were detected , it is suggested that the optimum poling condition is maintaining 15 minutes under 4kv / mm , poling temperature is 70 xrd results indicate that the fabric transited from rhombohedral to tetragonal gradually with the substitution of the ba2 + . morphotropic phase boundaries ( mpb ) of the ceramic exist in the composition range of x = 0 . 06 ~ 0 . 10
Xrd分析表明，随着ba ~ ( 2 + )取代量的增加，样品晶体结构逐渐由三方相向四方相转变，在x = 0 . 06 0 . 10组成范围内存在三方、四方相共存的准同型相界。
When the contents of the pb is larger than that of the sr , the crystalline phase structures is changed from the cubic phase structure to the tetragonal stucture . in another words , the tc temperature will increase with the pb contents , when the pb contends is equal to the sr contends , the tc temperatue is at about room temperature
当pb的含量超过sr的含量时，室温下的晶体结构发生变化，由原来的立方相结构变成四方相结构，也即居里点温度随pb的含量增加而提高，铅和锶的含量相等时居里点出现在室温附近。
On the base of tg - dta , found the yb : kgw crystal has very good thermal stability under 1100 , which has two obvious absorption peak at 1088 and 1025 , contrast with the pure kgw crystal ( melting point at 1005 , phase transition temperature from tetragonal system to monoclinic is 1075 ) , we know the yb : kgw crystal ' s melting point is the absorption peak at 1088 , phase transition peak from tetragonal system to monoclinic is the absorption peak at 1025
利用tg - dta对所生长的yb ： kgw晶体测定说明，其在1100以下的热稳定性是很好的。 yb ： kgw晶体在1088和1025有两个明显的吸收峰，判断在1088处较宽的吸收峰是yb ： kgw晶体的熔点， 1025处的吸收峰是yb ： kgw晶体从四方晶系向单斜晶系的相转变峰。
