growth during the sintering 中文意思是什麼
growth during the sintering
解釋
燒結時的生長-
For the ceramic materials, the effects of additives such as pbo, b2o3, co2o3, mno2, cr2o3, sb2o3 on the electrical properties of bismuth - free zno - glass varistor were studied. the glass phase formed mainly by pbo and b2o3 during sintering process could decrease the sintering temperature, improve grain uniform growth and inhibit grain second growth. nonlinear property could be improved by properly adding co2o3, mno2, and cr2o3
對瓷料而言，系統研究了非bi系zno -玻璃料配方體系中pbo 、 b2o3 、 co2o3 、 mno2 、 cr2o3 、 sb2o3等添加劑對壓敏電阻電性能的影響規律，其中， pbo 、 b2o3在燒結過程中形成的玻璃相，可降低燒結溫度，促進晶粒均勻生長，抑制晶粒二次長大， co2o3 、 mno2 、 cr2o3做為非線性添加劑，適量添加可提高樣品的非線性， sb2o3做為改性添加劑，在燒結過程形成的尖晶石相可細化晶粒，抑制晶粒二次生長，改善樣品的綜合電性能。 -
The impact toughness could be prominently improved by ag mainly because of the depressing of grain growth during the sintering, and some granuliform nd - rich phase appeared
Ag元素提高磁體沖擊韌性主要是因為細化了主相晶粒並使顆粒狀富nd相增多。 -
No remarkable grain growth has been found during the phase transformation annealing. high sintering densities over 83 % of theoretical ones have been obtained for the hot - pressed samples
實驗結果表明，熱壓試樣都有較高的燒結密度，緻密度均超過83 ，最高達到了99 。 -
Adding sic can decreases sintering temperature of al2o3 efficaciously, but also can make the al2o3 crystal growth as flake, strengthen the coalescent of the al2o3 crystals, and the residual sic during sintering can strengthen the al2o3 ceramics. because the reaction between sic and al2o3 begins from the surface of samples, there is a compact protecting field on the surface of the samples to restrain o2 enter into the samples, and leave more pore in them to decrease the thermal expansion coefficient and increase their the al2o3 ceramics " thermal shock resistanc e times
引入sic的樣品在燒結過程中，首先在樣品的表面產生sic與o _ 2及al _ 2o _ 3的反應，形成一層緻密的保護層，阻礙o _ 2進入材料內部，在材料的內部留下較大的氣孔率，可以降低其熱膨脹系數，並使材料在受熱過程中有一定的空間進行結構調整，能夠顯著的提高al _ 2o _ 3陶瓷材料的抗熱沖擊次數。
