Fused quartz ceramic and preparation method thereof
The invention belongs to the field of fused quartz ceramic material preparation, and particularly relates to fused quartz ceramic and a preparation method thereof. The quartz ceramic is prepared by carrying out cross-linking reaction on an organic monomer and a cross-linking agent, carrying out in-situ curing on fused quartz particles, and sintering, wherein the organic monomer is N-vinyl pyrrolidone (NVP), and the cross-linking agent is diallyl tartaric acid diamide (DAT). The fused quartz ceramic is prepared through the steps of slurry preparation, gel casting and curing, sintering molding and the like, organic monomer in the slurry is initiated by the initiator to polymerize and cure raw material particles in situ to form a three-dimensional cross-linked network structure with a uniform structure, and the prepared product has ideal density and mechanical strength; and the requirement for preparing large-size and thick products can be met.
本发明属于熔融石英陶瓷材料制备领域，尤其涉及一种熔融石英陶瓷及其制备方法。所述石英陶瓷由有机单体与交联剂经交联反应将熔融石英颗粒原位固化后烧结而成；其中，所述有机单体为N‑乙烯基吡咯烷酮（NVP），交联剂为二烯丙基酒石酸二酰胺（DAT）。本发明经过料浆制备、注凝固化、烧结成型等步骤制备得到熔融石英陶瓷，通过引发剂引发浆料中有机单体原位聚合固化原料颗粒形成结构均匀的三维交联网状结构，制备出的产品具有理想的致密度和机械强度，能够满足制备大尺寸及厚实制品的需求。
