Strontium titanate ceramic grinding ball and preparation method of high-purity strontium titanate ceramic
The invention provides a strontium titanate ceramic grinding ball. The strontium titanate ceramic has a general formula as shown in a formula (I): SrTixNbyV0.001 Ta 0.001 O3 (I). Strontium carbonate, titanium dioxide, niobium pentoxide, vanadium pentoxide and tantalum pentoxide are used as raw materials, the raw materials are uniformly mixed according to a certain proportion, ball milling, forming and sieving are performed, sintering and annealing are performed in an atmosphere sintering furnace, and the obtained grinding ball has good stability and wear resistance and is suitable for large-scale production. The method is specially used for a grinding process for preparing a strontium titanate ceramic material with a giant dielectric constant and low dielectric loss, and has the advantages of good grinding characteristic and almost no introduction of impurities. The invention further provides a preparation process of the strontium titanate ceramic material, the strontium titanate ceramic grinding balls are adopted, the purity and performance of strontium titanate ceramic can be improved, and therefore the strontium titanate ceramic material with the giant dielectric constant and low dielectric loss is obtained.
本发明提供了一种钛酸锶陶瓷研磨球，所述钛酸锶陶瓷具有如式(I)所示的通式：SrTixNbyV0.001Ta0.001O3(I)。本发明以碳酸锶、二氧化钛、五氧化二铌、五氧化二钒、五氧化二钽为原料，按照一定的配比混合均匀、球磨、成型过筛、在气氛烧结炉中烧结退火，得到的研磨球具有良好的稳定性和耐磨性，专门用于巨介电常数和低介电损耗的钛酸锶陶瓷材料制备的研磨工序，具有研磨特性好、几乎不引入杂质的优点。本发明还提供了钛酸锶陶瓷材料的制备过程，采用钛酸锶陶瓷研磨球，能够提高钛酸锶陶瓷的纯度和性能，从而得到了巨介电常数和低介电损耗的钛酸锶陶瓷材料。
