Description

一种高效环保熔融石英陶瓷的制备方法
技术领域
本发明属于石英陶瓷生产技术领域，具体地，涉及一种高效环保熔融石英陶瓷的制备方法。
背景技术
熔融石英陶瓷是一种以熔融石英为原料，采用陶瓷生产工艺制成的熔融石英材料。它不仅具有石英玻璃的许多优良性质，如热膨胀系数小、热稳定性好、电绝缘性好、耐化学侵蚀性好，而且还具有一些石英玻璃制品所缺乏的性质。国外生产熔融石英陶瓷制品的厂家主要有美国、法国、日本及俄罗斯的几家公司，而国内能生产熔融石英陶瓷制品的厂家却很稀少。
熔融石英是氧化硅的非晶态，由高纯石英砂高温熔融制得。因此要求高纯石英砂中的SiO2的纯度够高。现有技术对精制石英砂的提纯主要包括以下方法：磁选、酸浸及微生物浸出，因微生物浸出为新出方案，许多条件都在探索中，因此磁选和酸浸应用较为广泛，而酸浸的方案因采用的酸为浓度较高的HF、HCl、H2SO4和其它酸的混合，这些酸易挥发，腐蚀性较强，对人员身体健康损害较大，而且会污染环境；现有的磁选机对于精制石英砂的提纯无法进一步提高其纯度。
发明内容
针对现有技术存在的不足，本发明提供一种高效环保熔融石英陶瓷的制备方法，该种高效环保熔融石英陶瓷的制备方法可有效提高石英砂的纯度，而且无污染性，环保环境，制备得到的熔融石英陶瓷产品质量好，适宜于工业大规模推广应用。
为了达到上述目的，本发明通过以下技术方案来实现：一种高效环保熔融石英陶瓷的制备方法，其特征在于：包括如下步骤：
（1）将普通石英砂用破碎机进行破碎，破碎后过筛，然后用研磨机进行研磨，制成石英砂粉末；
（2）将石英砂粉末制成砂浆，然后用脱泥机进行脱泥；
（3）将脱泥后的石英砂中加入稀土合金，加入去离子水，搅拌使其混合均匀，得到混合砂浆；
（4）将混合砂浆采用磁选机进行磁选，磁选后得到高纯石英砂；
（5）将高纯石英砂于高温下熔融，然后快速冷却即可制得熔融石英砂；
（6）将熔融石英砂经粉碎机粉碎，然后加入去离子水制成料浆，浇注成型，得到陶瓷毛坯，将毛坯自然干燥后放入窑内进行烧结，烧结后取出冷却，对表面进行切割磨削，得到熔融石英陶瓷成品。
进一步地，所述步骤（1）中过筛的目数为100目。
进一步地，所述步骤（3）中石英砂与稀土合金重量配比为1:0.01-0.03。
进一步地，所述步骤（3）中稀土合金包括如下重量配比的组分：钆20-35份、铽15-25份、镝15-25份及钬25-45份。
进一步地，所述步骤（4）中高纯石英砂中的SiO2含量为99.8 %以上，Fe2O3含量为0.0005%以下。
进一步地，所述步骤（5）中熔融温度为1760 ℃。
进一步地，所述步骤（6）中最高烧结温度为1200 ℃，烧结时间为6-8 小时。
进一步地，所述步骤（6）中的冷却采用冷却水快速冷却。
有益效果：与现有技术相比，本发明具有以下优点：本发明提供的一种高效环保熔融石英陶瓷的制备方法，该种高效环保熔融石英陶瓷的制备方法在磁选前加入少量稀土合金与精制石英砂混合，稀土合金采用合适配比的重稀土元素钆、铽、镝及钬，它们均具有较强的铁磁性，与精制石英砂混合后，可将精制石英砂中所含的铁聚集起来，再由磁选机进行磁选，将稀土合金与铁分出，而分出的稀土合金还能重复回收利用，可有效提高高纯石英砂的纯度，进而提高熔融石英陶瓷的产品质量，而且此种制备方法不含污染性气体，不会污染环境，操作简便，适宜于工业大规模推广应用。
