Silicon dioxide ceramic material and preparation method thereof
The invention discloses a silicon dioxide ceramic material and a preparation method thereof, and belongs to the technical field of high-performance ceramic fillers. The material is prepared from the following raw materials in percentage by weight. The material comprises, by weight, 10-15% of silicon nitride, 10-15% of boron nitride, 5-10% of rare earth modified oxide whiskers, 3-5% of zirconium oxide and the balance silicon dioxide. Firstly, rare earth metal modified aluminum oxide whiskers are added into a matrix, and then a proper amount of boron nitride is added to increase the density of a system. Meanwhile, due to the use of silicon dioxide particles with different particle sizes, large-particle solids can promote uniform dispersion of small particles and other raw materials such as zirconium oxide, boron nitride and rare earth oxide whiskers, and agglomeration is reduced. The wave-transparent ceramic material has the advantages of favorable mechanical properties, low heat conductivity, low dielectric value, low dielectric loss, favorable thermal shock resistance, favorable processability and excellent comprehensive properties.
本发明公开一种二氧化硅陶瓷材料及其制备方法，属于高性能陶瓷填料技术领域。本发明材料包括以下重量百分比的原料制备而成；氮化硼10‑15%、稀土改性氧化物晶须5‑10%、氧化锆3‑5%、余量为二氧化硅。首先，本发明在基体中加入以稀土金属改性的氧化铝晶须，其次，加入适量的氮化硼，以增加体系致密度。同时不同粒度二氧化硅粒子的使用，大颗粒固体可以促进小颗粒以及其它原料，如氧化锆、氮化硼以及稀土氧化物晶须的均匀分散，降低团聚。本发明透波陶瓷材料，具有良好的力学性能，同时导热低、介电值小，介电损耗小，同时具有良好的抗热震性能以及可加工性，综合性能优异。
