中國(guo)各行業普遍使用(yong)的(de)(de)(de)(de)閥(fa)(fa)門(men)(men)為金(jin)屬(shu)閥(fa)(fa)門(men)(men)，金(jin)屬(shu)閥(fa)(fa)門(men)(men)的(de)(de)(de)(de)使用(yong)已有上百年的(de)(de)(de)(de)歷史，雖然(ran)金(jin)屬(shu)閥(fa)(fa)門(men)(men)經(jing)過(guo)結構及(ji)材(cai)料(liao)(liao)的(de)(de)(de)(de)改進，但受金(jin)屬(shu)材(cai)料(liao)(liao)屬(shu)性(xing)的(de)(de)(de)(de)限制，不(bu)能(neng)適應(ying)越(yue)來越(yue)高(gao)(gao)(gao)磨損、強(qiang)腐蝕等惡劣工況的(de)(de)(de)(de)需(xu)求(qiu)，主要(yao)體現在使用(yong)壽命短，泄露嚴重(zhong)大(da)(da)大(da)(da)影響了系(xi)統運行的(de)(de)(de)(de)穩定性(xing)。傳統的(de)(de)(de)(de)金(jin)屬(shu)閥(fa)(fa)門(men)(men)急需(xu)從材(cai)料(liao)(liao)、設計及(ji)制造(zao)工藝等方面的(de)(de)(de)(de)徹底革新。將陶(tao)(tao)瓷(ci)材(cai)料(liao)(liao)應(ying)用(yong)于工業閥(fa)(fa)門(men)(men)是一項大(da)(da)膽和有益的(de)(de)(de)(de)創新。陶(tao)(tao)瓷(ci)材(cai)料(liao)(liao)變形(xing)量(liang)很小，比金(jin)屬(shu)具有高(gao)(gao)(gao)得多(duo)的(de)(de)(de)(de)結合強(qiang)度(du)，一般(ban)情況下組成陶(tao)(tao)瓷(ci)材(cai)料(liao)(liao)的(de)(de)(de)(de)晶體離子半(ban)徑(jing)小，而(er)且離子電價高(gao)(gao)(gao)，配(pei)位數大(da)(da)，這些(xie)性(xing)質決定了陶(tao)(tao)瓷(ci)材(cai)料(liao)(liao)的(de)(de)(de)(de)抗拉強(qiang)度(du)、抗壓強(qiang)度(du)、彈(dan)性(xing)模量(liang)、硬度(du)等都非常高(gao)(gao)(gao)。然(ran)而(er)陶(tao)(tao)瓷(ci)本身的(de)(de)(de)(de)“脆(cui)”及(ji)難加工限制了它(ta)的(de)(de)(de)(de)應(ying)用(yong)范圍，近十幾(ji)年來，由(you)于馬氏體相變增韌技術(shu)、復合材(cai)科技術(shu)及(ji)納米陶(tao)(tao)瓷(ci)概念(nian)的(de)(de)(de)(de)發展及(ji)進步，已使陶(tao)(tao)瓷(ci)的(de)(de)(de)(de)“脆(cui)性(xing)”得到了大(da)(da)大(da)(da)改進，其(qi)韌性(xing)和強(qiang)度(du)得到了極(ji)大(da)(da)的(de)(de)(de)(de)提高(gao)(gao)(gao)，應(ying)用(yong)范圍不(bu)斷擴(kuo)展。
