Description
技术领域
本发明属于介质陶瓷材料领域,具体涉及一种铌酸钾钠宽温度稳定型陶瓷电容器介质材料及其制备方法。
背景技术
片式多层陶瓷电容器(MLCC)在整个电容器领域中占据着第一大分支的地位,因其具有尺寸小、电容量大、介电损耗低、击穿场强高和耐腐蚀等诸多优点被广泛地应用于各种军、民用电子整机和电子设备领域,如电视、电脑、电话、手机、汽车等产品和设备,目前已经成为应用最广泛的被动元件产品。
随着科技的发展,军工、航天、汽车电子等领域的工作需要在更极端的温度环境下进行,因此要求MLCC不仅要有较大的温度使用范围和稳定的温度性能,而且要有材料环保、低成本的制备工艺。传统的X7R和X8R型陶瓷电容器工作温度上限分别为125℃和150℃已不能胜任,X9R型电容器具有更宽的温度区间。根据国际电子工业协会(EAI)所发布的标准,X9R型MLCC器件的工作温度在-55℃到200℃的范围内。目前,用于制造高介电常数MLCC器件的材料主要有铅基复合钙钛矿体系、钨青铜结构体系、BaTiO3体系三类。铅基复合钙钛矿体系因为含铅不符合环保要求而正在被法律、法规禁止并逐渐被取代,钨青铜结构体系具有介电常数高但损耗大且不稳定,BaTiO3体系是目前大部分商用MLCC所采用的介质材料,但其居里温度比较低且工作温区较窄。无铅(K0.5Na0.5)NbO3体系陶瓷材料具有较高的居里温度(420℃),并且和BaTiO3体系一样具有钙钛矿结构,在以往的研究中被认为可以通过引入组分或掺杂改性,使其成为具有优异压电、铁电、介电、储能、应变等电学性能的新介质材料。
本发明对(K0.5Na0.5)NbO3陶瓷材料进行改性研究,通过引入其他组元与(K0.5Na0.5)NbO3形成固溶体,制备出了工作温度区间大、介电稳定性好的铌酸钾钠宽温度稳定型陶瓷电容器介质材料,在-60℃到300℃的范围内具有良好的介电稳定性。
发明内容
本发明的目的是提供一种介电稳定性高的铌酸钾钠基宽温度稳定型陶瓷电容器介质材料及其制备方法。
本发明所述陶瓷组份的化学通式为(1-x)(K0.5Na0.5)NbO3-xSr(In0.5Nb0.5)O3,其中x表示摩尔分数,0.1≤x≤0.2。
制备上述宽温度稳定型陶瓷电容器介质材料的具体步骤为:
(1)按照化学通式(1-x)(K0.5Na0.5)NbO3-xSr(In0.5Nb0.5)O3称量K2CO3、Na2CO3、SrCO3、In2O3和Nb2O5粉体原料进行配料,0.1≤x≤0.2。
(2)原料粉体加入无水乙醇球磨均匀混合,球磨浆料在90℃干燥,然后在950℃预烧5小时,冷却的预烧粉体研磨后再以950℃煅烧5小时。
(3)煅烧粉体用无水乙醇再次进行球磨破碎,90℃烘干后过筛,加入粘接剂造粒,用金属模具将粉体压制成圆片。
(4)将模压生坯放置在氧化铝承烧板上进行高温烧结,温度下降至600℃后停止加热,使炉温自然冷却至室温,然后取出陶瓷片。
