Description

一种氧化锗阻燃耐候性喷嘴
技术领域
本发明涉及碳化硼元件制备技术领域，具体涉及一种氧化锗阻燃耐候性喷嘴。
背景技术
陶瓷喷嘴自上个世纪九时年代引入中国以来，材料不断的改进更新，从氧化物陶瓷逐渐发展到氮化物陶瓷和碳化物陶瓷，而生产工艺及制备方法落后，致使现有技术中陶瓷喷嘴存在诸多缺陷，比如硬度不高、耐磨性差、防腐蚀防冲蚀能力弱、延展性不大等。为克服现有技术的不足，有必要对现有陶瓷喷嘴生产技术加以改进，从而制得适合不同需求的具有成本低、功能多元化、阻燃、硬度高、耐磨、防辐射等功能的陶瓷喷嘴。
碳化硼突出的优点是密度低、硬度高和中子吸收截面大，主要以碳化硼陶瓷材料的形式应用。碳化硼因强共价键结合，自扩散系数低，烧结困难。通常采用热压或者热等静压烧结才能实现致密化。但是，一方面热压和热等静压只能制备尺寸相对较小、形状简单的制品，另外一方面热压和热等静压的制造成本高，因此阻碍了碳化硼材料的应用。
发明内容
为实现上述目的，本发明提供一种氧化锗阻燃耐候性喷嘴。
本发明的目的可以通过以下技术方案实现：
一种氧化锗阻燃耐候性喷嘴，所述碳化硼喷头由以下重量份的材料组成：纳米碳化硼400-450份、金刚石粉1-2份、氧化钼2-4份、铝镁尖晶石4-8份、金红石5-8份、石蜡1-2份、硫酸钴0.1-0.3份、钾长石3-4份、白云石4-6份、石英3-8份、陶红泥7-11份、硝酸钾1-2份、氧化锗3-4份、氟硼酸钠2-4份、氮化铝3-5份、二硅化钼4-5份、二硼化钛4-5份、氢氧化镁0.7-1.3份、焦磷酸钠0.5-0.9份、钼酸钠0.3-0.5份。
所述碳化硼喷头由以下重量份的材料组成：纳米碳化硼420份、金刚石粉2份、氧化钼2份、铝镁尖晶石5份、金红石6份、石蜡1份、硫酸钴0.2份、钾长石3份、白云石5份、石英5份、陶红泥8份、硝酸钾1份、氧化锗3份、氟硼酸钠3份、氮化铝4份、二硅化钼4份、二硼化钛4份、氢氧化镁1份、焦磷酸钠0.6份、钼酸钠0.5份。
