陶瓷材料變形量很小，比金屬具有高得多的結(jié)合強(qiáng)度，一般情況下組成陶瓷材料的晶體離子半徑小，而且離子電價(jià)高，配位數(shù)大，這些性質(zhì)決定了陶瓷材料的抗拉強(qiáng)度、抗壓強(qiáng)度、彈性模量、硬度等都非常高。
陶瓷閥門的產(chǎn)品性能特點(diǎn)所有與介質(zhì)接觸的部分均為結(jié)構(gòu)陶瓷材料其化學(xué)穩(wěn)定性及硬度極高洛氏硬度僅次于金剛石。因此本閥具有極高的耐磨損、耐腐蝕、耐沖蝕性能，且隔熱性好、熱膨脹小。球體采用先進(jìn)研磨設(shè)備及工藝制造球圓度精度高表面質(zhì)量好與閥座對(duì)研后利用>陶瓷的自滑潤(rùn)性可取得很好的密封性能。
徹底改變了金屬硬密封球閥易泄露、扭矩大、密封面不耐腐蝕的缺點(diǎn)。陶瓷良好的耐磨性讓本閥經(jīng)久耐用可靠性極高使用壽命長(zhǎng)是鈦合金閥和蒙乃爾閥的2-4倍。用于高硬度的顆粒介質(zhì)，或有軟顆粒但又有腐蝕的介質(zhì)中，本閥門具有無可比擬的優(yōu)勢(shì)，也是目前合適此類介質(zhì)的閥門。（圖/文m.jiacaiys.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.
