The characteristic of phase transformation and microstructure evolution of Ti -based cermets has also been studied.

对细晶粒Ti基金属陶瓷烧结过程中的相变和组织结构变化规律进行了研究。

In this paper, the heat changes and sintering mechanism of various Chinese high-alumina clays are discussed.

本文讨论了我国各地高铝矾土加热过程的变化和烧结机理。

At a lower temperature (≤1600℃), CaO clinkers were fabricated using high grade limestone with Al_2O_3 as additive.

在较低温度下(≤1600℃)，将添加Al_2O_3的高纯石灰石在不同煅烧温度下制得了CaO烧结熟料。

Clinkers are nodules (diameters, 0.2-1.0 inch [5-25 mm]) of a sintered material that is produced when a raw mixture of predetermined composition is heated to high temperature.

水泥熟料是一种烧结的小颗粒(直径通常是0.2-1.0'')，由预先确定了化学成分的生料混合物加热至高温而得到的。

Crucibles were not significantly affected by microwave interaction and sinter cakes decomposed instantly and remained in solution for long periods of time.

微波没有显着影响坩埚，和烧结矿即时分解和长时间维持在液体中。

The results show that the best sintering process for SiC preform is 1100℃, 8 h in vacuum, by which the open porosity is 99.6% and the preform strength reaches 0.57MPa. The thermo-physical characteristics of 57% SiC/Al composites produced by this technique are as follows: the relative density is 98.7%; the thermal expansion coefficient is 7.5×10^(-6)℃^(-1) which almost matches those of GaAs and BeO; the thermal conductivity is 1.65×10^5W/K, which corresponds to that of Cu(15%)/W and decuples that of Kovar alloy; the density is close to that of aluminum and less than that of one fifth of Cu/W.

结果表明：经1100℃真空烧结8h的SiC预成形坯开孔率可以达到99.6%，抗压强度为0.57MPa；所制备的57%SiC/Al复合材料相对密度为98.7%，热膨胀系数为7.5×10^(-6)℃^(-1)，与GaAs、BeO的接近，热导率为1.65×10^5W/K，与传统Cu(l5%)/W相当，是柯伐合金的10倍，在密度上接近Al，不到Cu/W的1/5。

After effective dispersion measures taken, SGDC can fully densified at the sintering temperature of 1300℃.

这个温度比以前文献中所报道的1400～1600℃的烧结温度要低得多。

With the help of large plasma generation and the pressure, both of the samples sintered at 900℃ and 1100℃ are densified.

这主要是由于等离子体的产生，从而破坏粉末表面氧化物薄膜，使样品表面清洁得以充分接触，加之烧结的时间较短和压力的施加等因素造成的。

The densified and partially or fully stabilized ZrO2 ceramics were obtained by sintering the powder under 1550℃.

在1550℃烧结得到致密的部分稳定或稳定ZrO2试样。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
