Abstract
本发明涉及一种烧结制品，其由含有75％～99％锆石，和具有下述重量平均化学组成的始料而制造，基于氧化物重量百分数计：60％≤ZrO2+HfO2≤75％；27％≤SiO2≤34％；0.2％≤TiO2≤1.5％；0.3％＜Y2O3≤3.5％；和其它氧化物：≤1％；总计100％。还涉及所述烧结制品在玻璃熔炉中的应用。
Description
技术领域
本发明涉及由锆石制造的新型烧结物料、制造其的方法以及其在玻璃熔炉中的应用。
背景技术
耐火制品包括熔铸制品和烧结制品。
相比于烧结制品，熔铸制品通常包括丰富的晶间玻璃相，该晶间玻璃相填充结晶颗粒的晶格。因此，烧结制品和熔铸制品在其各自应用中所遇到的问题，以及用于解决该问题的技术方案通常是不同的。另外，由于在制造方法中的主要区别，先验地，用于制造熔铸制品的组合物不能被用于制造烧结制品，反之亦然。
烧结制品的获得是通过混合适宜的起始原料，然后定形该未加工的混合物，并于一定温度烧制由此形成的未加工形式，且保持足够的时间以获得该未加工形式的烧结物。
取决于烧结制品的化学组成和其制备方式，可以将该烧结制品用于多种工业产业。
先验地，一种适合于一个特定用途的烧结制品因而不具有用于另一用途所必需的特性，其中温度，腐蚀性，或者磨损情况都是不同的。
作为一个实例，美国专利US-A-3 899 341描述了由锆石(50～90％)和氧化锆制备的烧结制品。所述氧化锆被部分稳定以限制制品的弹性形变，该形变导致裂缝。然而，US-A-3 899 341所述的制品被设计成用于与熔融的钢相接触。因此，先验地，该烧结制品不适合用于与熔融态玻璃接触。
对于烧结制品，由锆石(锆的硅酸盐：ZrO2.SiO2或ZrSiO4)和可能地由氧化锆(锆的氧化物：ZrO2)所制造的致密制品可以被用于其直接与熔融态玻璃相接触的地方，尤其是与非碱性玻璃相接触。
因此，欧洲专利EP-A-0 952 125描述了准备用于玻璃熔炉的并且由锆石(5～40％)和氧化锆所制造的烧结制品。这些制品还包括钛、铝和钇的氧化物以使得可以制造大块无缝产物。这些制品中的SiO2含量小于14％。其ZrO2+HfO2的含量大于82％。
国际专利申请WO-A-02/44102描述了用于制造玻璃板的“isopipes”。按重量计，isopipes包括大于95％的锆石和其蠕变特性不充足除非其也包括了介于0.2％和0.4％之间的氧化钛。为了说明现有技术，WO-A-02/44102引用了US-A-5 124 287。
US-A-5 124 287描述了含有75％～95％的锆石和氧化钛的组合物，其意图与熔融态玻璃相接触。该文献指出氧化钛的存在有利于使烧结后所获得的产物增密。在最终产物中，氧化锆必须是未被稳定的，因此优选在起始的混合物中使用未被稳定的氧化锆。然而，使用已被稳定的氧化锆，例如带有诸如氧化钇或氧化钙之类的氧化锆稳定剂，并不是问题，因为对这些混合物加热导致破坏所述氧化锆的稳定。
在应力(压缩、张力或弯曲)作用下物料的蠕变可以被定义为一种物料在该负荷作用下发生弹性形变的能力，即永久地形变。耐火陶瓷的蠕变通常是热激活的，即温度的提高往往是增加该物料的蠕变率。
对于应用于某些玻璃，尤其是当定形玻璃板时，必须尽可能地限制蠕变至最小程度，因为蠕变可以在耐火块上造成一定形变以至导致很难与玻璃板的尺寸规格相一致，并且造成玻璃制造者的巨大损失。
发明内容
因此，需要一种具有改进的蠕变强度的制品，该制品能被用于玻璃熔炉。本发明的目的在于满足这一需要。
为此目的，本发明提出一种烧结制品，其由含有75％～99％锆石，并具有下述重量平均的化学组成的始料而制造，基于氧化物的重量百分数计：
·60％≤ZrO2+HfO2≤75％；
·27％≤SiO2≤34％；
·0.2％≤TiO2≤1.5％；
·0.3％＜Y2O3≤3.5％；和
·其它氧化物：≤1％；
总计100％。
如下所说明，相比于以前所描述的制品，所述烧结耐火制品具有改进的蠕变强度。
优选地，本发明的制品优选地表现出一种或多种下述可选择的特性：
·基于氧化物的重量百分比计，在始料中锆石的量为80％或更多；
·基于氧化物的重量百分比计，氧化锆的含量大于5％，优选大于10％，和/或小于15％；
·氧化锆至少部分地被氧化钇所稳定，按重量百分比计，被稳定的氧化锆在氧化锆中大于10％，优选大于20％；
·基于氧化物的重量百分比计，氧化钇(Y2O3)的总量是1.7％或更少和/或是0.7％或更多。超过1.7％时，主晶相可以被显著改变，造成物料硬度的增强，或甚至造成可行性问题。
本发明还提供了一种制造烧结制品的方法，其包括下述步骤：
a)混合起始原料以形成始料；
b)从所述始料中定形一未加工部分；和
c)烧结所述未加工部分以获得所述的烧结制品；
该方法值得注意的是确定始料以便所述制品与本发明相一致。
优选地，在步骤a)中，按基于氧化物的重量百分比计，添加单斜相氧化锆和/或包括至少1％氧化钇的氧化锆，和/或至少1％二氧化硅到始料中，所述氧化钇不与氧化锆缔合(not associated with zirconia)。
也优选，在步骤a)中，按基于氧化物的重量百分比计，添加锆石和可选择地添加氧化锆以使得在始料中锆石和氧化锆的总量至少95％。
本发明还提供了根据本发明的耐火制品在玻璃熔炉中的用途，尤其是熔炉中与熔融态玻璃接触的区域。
在本发明的说明中并且按照惯例，术语“氧化锆”被用于表示ZrO2分子，其没有和SiO2分子缔合而形成锆石。类似地，术语“二氧化硅”被用于表示SiO2分子，其不与ZrO2分子缔合而形成锆石。
除非另有说明，所有的百分数都基于氧化物的重量百分比计。
可以由锆砂或者由具有高锆石含量的致密制品的熟料提供锆石。
通过化学分析确定，本发明的组合物只提供了SiO2和ZrO2的总量而没有区分相应的锆石的量。
根据本发明，需要始料包括至少75％，优选至少80％的锆石。事实上，如果由根据本发明的锆石所提供的大量SiO2和ZrO2是以二氧化硅或氧化锆的形式提供，则不会获得本发明制品的有益特性。
优选地，在始料中锆石和氧化锆的总量是至少95％。
含有氧化锆的起始原料也含有少量HfO2(1.5％～2％)，和通常的，这两种氧化物彼此不被区分。
由于在高温时氧化锆的结晶状态的改变，氧化锆显示出巨大的膨胀变化。为了限制这些膨胀变化，尤其是在大块制品中，必须限制氧化锆的含量。因此，始料必须含有少于25％的氧化锆，这在锆石含量至少是75％时可以保证。
优选地，在本发明制品中的氧化锆至少部分被氧化钇所稳定，按重量百分比计，氧化锆中被稳定的氧化锆大于10％。为此目的，氧化锆必须以未被稳定的形式被引入和氧化钇必须被个别地添加到始料中。
另外，如下表3所说明，氧化锆被氧化钇所稳定是很重要的。用于氧化锆的常规稳定剂，例如氧化镁或生石灰，已被证明对物料的蠕变强度具有负面的作用。
根据本发明，氧化钇的存在改进了锆基耐火制品的蠕变强度。如果将氧化锆添加到始料中，使用氧化钇所稳定的氧化锆可以被用于提供氧化钇。如下所说明，氧化钇优选独立于氧化锆地被添加到始料中以促进，至少部分地促进，本发明制品中的氧化锆的稳定。
然而，优选氧化钇并不稳定太大量的氧化锆。因此氧化钇的含量被限制到3.5％。
本发明制品中的SiO2的含量相应于锆石的SiO2含量和游离的二氧化硅。优选地，至少1％的二氧化硅被添加到始料中以促进在低于纯锆石增密所需的温度下引发增密。
通常在具有高锆石含量的烧结制品中，TiO2的总量为0.2％～1.5％。TiO2可以促进锆石的烧结和促进在烧结时制品增密。
所述“其它氧化物”是例如Na2O，Al2O3，P2O5或Fe2O3的氧化物。Na2O(可促进锆石分解)和Fe2O3的含量必须被最小化。它们是由起始原料所提供的，不是必要的组成，而仅仅是可被容忍的。
具体实施方式
为了说明本发明，下面给出非限制性实施例。
在这些实施例中，所使用的起始原料选自(给定的百分数为重量百分数)：
·锆砂，其含有66.8％的ZrO2+HfO2，32.7％的SiO2，0.2％的Al2O3和0.1％的TiO2；
·氧化锆，例如由Saint-Gobain ZirPro出售的CS10或CC10。这些产品含有至少98.8％的ZrO2+HfO2和0.1％～0.5％的SiO2和具有约3.5μm(微米)的中位粒径(D50)；
·钇稳定的氧化锆(yttriated zirconia)，其含有92％的ZrO2+HfO2，7％的Y2O3，0.3％的Al2O3和0.2％的TiO2。其中位粒径(D50)为大约11μm；
·氧化钛，其含有96.6％的TiO2，1.7％的Fe2O3，0.8％的SiO2和0.6％的Al2O3；
·纯度大于99.9％的纯氧化钇，其中位粒径大约3μm～4μm；
·磷酸(85％H3PO4溶液)；
·晶状二氧化硅，其含有大于98％的SiO2和中位粒径为大约10μm。
使用常规方法制造烧结的耐火块，所述方法包括下述步骤：
a)可选择地研磨锆石源；
b)混合起始原料以形成始料；
c)由所述混合物定形未加工部分；
d)烧结所述未加工部分。
步骤a)可以制造出对于物料的良好的随后增密所需的常规粒度特性。在此所描述的实施例中，所制备粉末具有小于5μm的中位直径(D50)。
在步骤b)中，所有起始原料都被进行含量测定以便该混合物具有按重量计的所需平均化学组成，然后在通常被用于锆石烧结方法中的粘合剂存在的情况下混合该原料，所述粘合剂例如磷酸。
可选择地，在移至步骤c)之前起始原料可以被粉碎成小颗粒。
然后在步骤c)中，通过等静压定形该混合物以形成所需尺寸的大块(100mm×100mm×150mm)。
也可使用其它技术，例如振动压铸。
然后在步骤d)中，在大气压下和在1400℃～1700℃的温度下，将定形的部分在空气中烧结以形成致密耐火块。
从各种块中取出样品以进行性能测试。
在一个“等温”蠕度检测中，使用四点弯曲试验(外侧点之间的距离L＝110mm(毫米)，内侧点之间的距离l＝40mm)。将尺寸为25mm×15mm×150mm的棒放置到这些点上然后对其中心施加2MPa的应力，保持温度为1275℃不变。在整个试验中测定该棒的变形量的变化(毫米)。比较不同测试样品的Df15和Df90值，即分别在15小时和90小时后的形变百分数。
在气泡试验中，制品的测试样品组成一个壁厚5mm且内径30mm的圆柱形坩埚。用硼硅铝酸盐型玻璃(boro-silico-aluminate type glass)装填这一坩埚。然后在空气中将坩埚加热到1350℃并保持70小时。一旦完成热处理，将坩埚冷却然后锯开以切割玻璃。然后通过肉眼观察玻璃切口。使用等级1(最小起泡)～10(强烈起泡或起沫)确定起泡指数BI，其作为冷却后玻璃中所捕获的气体气泡数的函数。当起泡指数是5或更小时，认为该指数良好。
为了评价耐腐蚀性，将直径20mm和长度100mm的样品在1400℃，于硼硅铝酸盐型玻璃中转动180小时。一旦完成热循环，从玻璃中将样品取出并测定样品的体积和将其与初始体积进行比较。将测试样品的被腐蚀的体积和参考样品的被腐蚀的体积的比率乘以100后确定腐蚀指数CI。
表1中显示了起始原料的混合物的组成(基于混合物的重量百分数)。
参考制品是制品No.1。

表2给出了各种测试制品的平均化学分析和测试结果(基于氧化物的重量百分数)。表中没有显示例如Al2O3，P2O5，Fe2O3等的次要氧化物的含量。所述次要氧化物的总量小于1％。

| 8 | 68.8 | 29.1 | 1.0 | 0.24(CaO) | 1.33 | ND |
ND：没有数据，是由于在蠕变测试结束前棒的过量形变和断裂造成的。
这些实施例显示出添加氧化钇可以非常显著地减少由蠕变产生的形变。
添加氧化钇并不使物料的其它特性退化。事实上，其腐蚀指数与参考产品的腐蚀指数相同。另外，本发明的制品可以轻度改善起泡。
制品No.4具有最佳的蠕变强度。其与实施例6的比较显示了优选提供氧化锆。优选地，始料包括至少5％，优选至少10％的氧化锆。
实施例4和5的比较也显示优选在始料中提供不与氧化锆缔合形式的氧化钇而不是添加钇稳定的氧化锆。优选地，始料中包括至少1％的不与氧化锆缔合的氧化钇(即不是作为用于氧化锆的稳定剂)。
另外，晶体学分析显示一种由被晶间相所围绕的锆石颗粒组成的结构，其主要包括氧化锆和二氧化硅。对于本发明的制品，氧化钇在晶间相中结合了氧化锆并且氧化钇不被引入到锆石颗粒中。
使用实施例1和5的制品所进行的互补压缩强度试验证明了本发明制品的改进的性能。
实施例7和8显示了不是使用全部的用于氧化锆的稳定剂都可获得所期望的结果，所述稳定剂例如氧化镁或生石灰。事实上，已经显示出这些稳定剂对物料的蠕度强度是具有负面作用的。
显然，本发明不限于以说明性实施例的方式所提供的具体实施方式。
特别地，本发明的制品并不限于使用上述方法所制造的制品。任何由锆石制造烧结制品的已知方法都是适宜的。
