We defined the standards for near-zero sintering shrinkage pottery (NZS) fired -1300 degrees based on expert suggestions, as follows: i) sintering shrinkage (SS) of <2.0%; ii) pyroplastic deformation index (PI) of <1.5×10-6 mm-1.Then, we analyzed the thermal mechanical properties and phase composition of NZS. The sintering shrinkage of NZS stops at 1100～1200 degrees due to anorthite crystallization, confiremed by high-temprature XRD. After analyzing the phase composition of the pottery fired at 1200 degrees and the pottery with SS <2.0% fired at 1300 degrees, respectively, phase composition criteria of NZS was established, and the suppressing mechanism was clarified.

我们根据专家建议定义了接近零烧结收缩陶器（NZS）的标准，如下所示：i）烧结收缩（SS）<2.0％； ii）<1.5×10-6 mm-1的塑性变形指数（PI）。然后，我们分析了NZS的热机械性能和相组成。 NZS的烧结收缩因北力石结晶而停止在1100-1200度，并由高速XRD证实。在分析以1200度发射的陶器的相组成和分别在1300度下射出的陶器发射的陶器后，建立了NZS的相组成标准，并阐明了抑制机制。
