A new synthesis technique for BSTN composite ceramics

Strontium barium niobate/barium strontium titanate(BSTN in short) was prepared through a modified sol-gel technique,by controlling the ratios of different components in the sol solution to suspend the fine strontium barium niobate powders(SBN in short)which was made beforehand by traditional ceramic sintering technique.After about half an hour dispersing under the ultrasonic wave,transparent gel can be gained.In the end the ceramic body was made out.X-ray diffraction(XRD) and scan electron microscope(SEM) were chosen to test the ceramics character and at the same time,the sintering technique was also studied.The results showed that this new synthesis technique posses advantages such as easy control,low cost,and can inhibit the abnormal grain growth in the sintering process,anyway,we present a new synthesis techniques for scientific research.
