Abstract

本发明提供了一种陶瓷材料的热处理方法及用于陶瓷材料热处理的脱模纸，包括以下步骤：一将密度为2.4‑2.6g/cm3的陶瓷母坯置于模具中，陶瓷母坯之间置有脱模纸，所述模具为石墨或氧化铝模具；二将上述模具置于空气气氛炉中或氮气气氛炉中进行热处理：以3‑5℃/min的升温速率自室温升至820‑900℃，在820‑900℃保温1‑2h后，冷却至室温后取出。经过高温燃烧之后的灰分或者无氧高温碳化后的碳可以均匀地在陶瓷母坯之间形成隔离，同时不与陶瓷母坯发生反应，同时脱模纸因为有纤维素和半纤维素的存在，具有较高的耐折度，在实际使用的过程中，更容易方便地放置在各层陶瓷母坯间，成本相比于其他脱模剂或脱模方法更低。

Description

一种陶瓷材料的热处理方法及用于陶瓷材料热处理的脱模纸
技术领域
本发明属于陶瓷制造的技术领域，具体涉及一种陶瓷材料的热处理方法及用于陶瓷材料热处理的脱模纸。
背景技术
二十一世纪是电子产品的时代，在手机、可穿戴设备的背板的保护材料上，大家需要质轻的、抗摔的、美观的陶瓷背板材料，而陶瓷材料在长晶的过程中为了提高热处理的效率，在晶化的过程中会叠片进行热处理，叠片在高温下热处理需要中间有隔离片用来防止陶瓷在高温下黏连，常规的分片脱模剂常会选用无机耐高温的粉末材料，例如六方氮化硼，但是六方氮化硼的脱模剂成本较高，同时六方氮化硼粉末在700℃以上会部分受热分解产生氧化硼，氧化硼会与轻质陶瓷中的组分产生化学反应，产生其他类型的晶体，例如ZrN，会造成轻质陶瓷的的机械性能降低，除此之外，硼的离子半径仅有20pm，更易渗入陶瓷母坯中，有成核剂的作用，从而使陶瓷母坯中的晶粒过分长大，形成大量的晶界孔洞，不利于陶瓷材料的机械性能。
发明内容
为克服现有脱模剂的脱模方案的不足，本发明所要解决的技术问题是提供一种陶瓷材料的热处理方法及用于陶瓷材料热处理的脱模纸，在节约成本的同时提供材料最佳的机械性能，使用方法更加简单无害，本发明解决技术问题所采用的技术方案是：一种陶瓷材料的热处理方法，包括以下步骤：
步骤一：将密度为2.4-2.6g/cm3的陶瓷母坯置于模具中，陶瓷母坯之间置有脱模纸，所述模具为石墨或氧化铝模具；
步骤二：将上述模具置于空气气氛炉中或氮气气氛炉中进行热处理：以3-5℃/min的升温速率自室温升至820-900℃，在820-900℃保温1-2h后，冷却至室温后取出。
所述步骤一中的脱模纸为由50-90wt％纤维素，20-30wt％半纤维素，20-30wt％木素，0.1-1wt％树脂和0.2-1wt％灰分组成，其中灰分为钾、钠、钙、镁、硫、磷、硅的盐类。
所述脱模纸的厚度为0.1-1mm。
所述脱模纸能在700-900℃下空气气氛中燃烧或氮气气氛下碳化。
所述脱模纸的耐折度为300-600。
进一步的，所述陶瓷母坯的组成为68-74wt％SiO2，5-9wt％Al2O3，0-1wt％TiO2,0-1wt％CaO，9-13wt％Li2O，0.1-1.5wt％Na2O，0.1-1wt％K2O，3-6wt％P2O5，3-9wt％ZrO2，0-1wt％BaO，0-3wt％MgO，0-2wt％ZnO和0-2wt％Sb2O3。
一种用于陶瓷材料热处理的脱模纸，其由50-90wt％纤维素，20-30wt％半纤维素，20-30wt％木素，0.1-1wt％树脂和0.2-1wt％灰分组成，其中灰分为钾、钠、钙、镁、硫、磷、硅的盐类。
所述脱模纸的厚度为1-100μm，能在700-900℃下燃烧或碳化，其耐折度为300-600。
现有技术中，使用的脱模剂通常为耐高温的物质，例如六方氮化硼，但是对于本申请中提到的陶瓷母坯，由68-74wt％SiO2，5-9wt％Al2O3，0-1wt％TiO2,0-1wt％CaO，9-13wt％Li2O，0.1-1.5wt％Na2O，0.1-1wt％K2O，3-6wt％P2O5，3-9wt％ZrO2，0-1wt％BaO，0-3wt％MgO，0-2wt％ZnO和0-2wt％Sb2O3组成，会与六方氮化硼会发生化学反应，导致材料的性能降低。本发明的脱模纸主要成分的纤维素、半纤维素不耐高温，一般很难被想到用作需要耐高温的脱模剂，但是经过高温燃烧之后的灰分或者无氧高温碳化后的碳可以均匀地在陶瓷母坯之间形成隔离，同时不与陶瓷母坯发生反应，同时脱模纸因为有纤维素和半纤维素的存在，具有较高的耐折度，在实际使用的过程中，更容易方便地放置在各层陶瓷母坯间，成本相比于其他脱模剂或脱模方法更低。
