陶瓷材料变形量很小，比金属具有高得多的结合强度，一般情况下组成陶瓷材料的晶体离子半径小，而且离子电价高，配位数大，这些性质决定了陶瓷材料的抗拉强度、抗压强度、弹性模量、硬度等都非常高。
陶瓷阀门的产品性能特点所有与介质接触的部分均为结构陶瓷材料其化学稳定性及硬度极高洛氏硬度仅次于金刚石。因此本阀具有极高的耐磨损、耐腐蚀、耐冲蚀性能，且隔热性好、热膨胀小。球体采用先进研磨设备及工艺制造球圆度精度高表面质量好与阀座对研后利用>陶瓷的自滑润性可取得很好的密封性能。
彻底改变了金属硬密封球阀易泄露、扭矩大、密封面不耐腐蚀的缺点。陶瓷良好的耐磨性让本阀经久耐用可靠性极高使用寿命长是钛合金阀和蒙乃尔阀的2-4倍。用于高硬度的颗粒介质，或有软颗粒但又有腐蚀的介质中，本阀门具有无可比拟的优势，也是目前合适此类介质的阀门。（图/文www.yxwdcy.com）

Ceramic material deformation is small, with much higher bond strength than metal, typically consisting of ceramic material crystal ionic radius is small, and the ion electrovalency is tall, coordination number, which determines the nature of the ceramic material tensile strength, compressive strength, elastic modulus, hardness and so on are very high.

Ceramic valve product performance characteristics of all contacts with the media parts structural ceramic materials and its chemical stability and very high hardness of Rockwell hardness second only to diamond. The valve has high wear resistance, corrosion resistance, erosion resistance, and good heat insulation, small thermal expansion. The ball using advanced grinding equipment and process for manufacturing high precision ball roundness good surface quality and the seat of the study using > ceramic self lubricating can be achieved very good sealing performance.
