In this paper, we have quantified and investigated the effect of various sintering temperature on close-packed Silica Nanospheres (SNs) monolayers. SNs with diameters of 140, 175 and 220 nm were fabricated by an effective and reliable spin-coating technique. The fabricated SNs monolayers were sintered up to 1200 °C and were analyzed from FESEM to investigate in details for local and extended transformations in their structural and morphological properties. A distinct "neck-formation" was observed and was quantified with different particle size distribution as well as surface packing density. It was observed that SNs monolayer undergoes intra-particle reformation in the form of shrinkage in individual SNs and compactification of growth domains, followed by inter-particle sintering. A geometrical model was developed to determine the curvature radius and interpenetration depth thus enabling us to quantify the parameters that dominate the dynamics of the sintering process for such non-porous SNs.

在本文中，我们已经量化并研究了各种烧结温度对紧密堆积的二氧化硅纳米球（SNs）单层的影响。通过有效和可靠的旋涂技术制造了直径为140、175和220 nm的SN。将制成的SNs单层烧结至1200°C，并通过FESEM进行分析，以详细研究其结构和形态特性的局部和扩展转变。观察到明显的“颈部形成”，并用不同的粒度分布以及表面堆积密度进行了定量。观察到，SNs单层以单个SN中的收缩形式和生长域的致密化形式经历了颗粒内重构，然后进行了颗粒间烧结。
