Experiments on the high efficiency thinning and ultra-smooth polishing of alumina piezo ceramic substrates were carried out for processing methods, abrasives and processing parameters.The mechanism of influencing factor was further studied through process experiments, and the processing paramete

Alumina piezo ceramics are often formed by hot sintering. Since sintering usually causes deformation and shrinkage, it is generally required. To ensure the dimensional accuracy and shape accuracy of the workpiece. However, due to the general elasticity of alumina piezo ceramics materials.The modulus

Nowadays,piezo ceramics have been widely used in the electronics, chemical, military and otherfields due to their high hardness,strengths, excellent corrosion resistance and insulatingproperties. As the compositions of piezo ceramics and raw materials are key factors to determinethe performance, the

1.Medical ultrasound imaging technology is the four medical imaging technologies of modern medical imaging technology, and has been widely used in the cardiology, obstetrics, ophthalmology, liver, kidney, gallbladder and vascular system. Compared with other imaging technologies, ultrasound imaging
