Description
本發明係關於一種無機組成物物品。
各種的無機材料作為用以保護智慧型手機、平板型PC(Personal Computer;個人電腦)等的可攜式電子機器的顯示器所用之保護玻璃(cover glass)或框體,再者,作為用以保護車載用的光學機器的鏡片所用之防護器(protector)或內裝用的擋板(bezel)和控制面板(console panel)、觸控面板素材、智慧型鑰匙等之使用受到期待。然後,這些機器尋求使用在嚴酷的環境,針對具有更高硬度的無機材料之要求正逐漸增強。進而,隨著用途而尋求高透明性或著色度低。
作為經提高玻璃的強度者,有著結晶化玻璃。結晶化玻璃係使結晶析出於玻璃內部而成,因機械強度比非晶形玻璃更為優秀而被熟知。進而,作為提高結晶化玻璃的強度之方法,已知有化學強化。
專利文獻1中,揭示著資料記錄媒體用無機組成物基板的材料組成。專利文獻1所記載之α-白矽石系無機組成物物品被記敘著可化學強化,能夠用作強度高的材料基板。但是,關於以硬碟用基板為代表之資料記錄媒體用結晶化玻璃,並非預想使用在嚴酷的環境,亦沒有尋求透明性。

再者作為玻璃的澄清劑,除了Sb

無機組成物物品能夠利用以下的方法來製作。亦即,以各成分成為預定的含量之範圍內的方式將原料均勻地混合,進行熔解成形來製造原材(original material)物品。其次將該原材物品進行結晶化來製作本發明的無機組成物物品。
用以結晶析出的熱處理,能以1階段亦能以2階段的溫度進行熱處理。
在2階段熱處理,首先於第1溫度進行熱處理,藉此進行晶核形成步驟,在此晶核形成步驟之後,於比晶核形成步驟更高的第2溫度進行熱處理,藉此進行結晶成長步驟。
2階段熱處理的第1溫度較佳為能夠設為450℃至750℃,更佳為500℃至720℃,進而較佳為550℃至680℃。在第1溫度的保持時間較佳為30分鐘至2000分鐘,更佳為180分鐘至1440分鐘。
2階段熱處理的第2溫度較佳為能夠設為550℃至850℃,更佳為600℃至800℃。在第2溫度的保持時間較佳為30分鐘至600分鐘,更佳為60分鐘至400分鐘。
在1階段熱處理,以1階段的溫度連續地進行晶核形成步驟與結晶成長步驟。通常,昇溫至預定的熱處理溫度,在到達該熱處理溫度後保持該溫度一定時間,之後進行降溫。
以1階段的溫度進行熱處理的情況,熱處理的溫度較佳為600℃至800℃,更佳為630℃至770℃。再者,於熱處理的溫度的保持時間較佳為30分鐘至500分鐘,更佳為60分鐘至400分鐘。
能夠將所獲得之無機組成物物品加以強化而在表面形成壓縮應力層。作為強化方法,例如有使存在於無機組成物物品的表面層之鹼性成分與離子半徑比該鹼性成分更大的鹼性成分進行交換反應,在表面層形成壓縮應力層之化學強化法。再者,有將無機組成物物品進行加熱,之後進行驟冷之熱強化法;在無機組成物物品的表面層植入離子之離子植入法。
化學強化法例如能夠利用如下述的步驟來實施。使無機組成物物品接觸或浸漬於含有鉀或鈉的鹽(例如硝酸鉀(KNO
3)、硝酸鈉(NaNO
3)或是該鹽的混合鹽或者複合鹽)之熔融鹽。接觸或浸漬於此熔融鹽之處理(化學強化處理)能以1階段亦能以2階段來處理。
關於熱強化法並沒有特別限定,例如藉由將無機組成物物品加熱至300℃至600℃後,實施水冷及/或氣冷等之急速冷卻,藉著玻璃的表面與內部之溫差而能夠形成壓縮應力層。另外,藉由與上述化學處理法組合,亦能夠更有效地形成壓縮應力層。
關於離子植入法並沒有特別限定,例如使任意的離子以不會破壞表面之程度的加速能量、加速電壓撞擊到無機組成物物品表面,藉此將離子植入到表面。之後視需要進行熱處理,藉此與其他方法同樣地能夠在表面形成壓縮應力層。
[實施例]
實施例1至實施例38、比較例1
作為結晶化玻璃之各成分的原料,選定各個相稱的氧化物、氫氧化物、碳酸鹽、硝酸鹽、氟化物、氯化物、偏磷酸化合物等之原料,將這些原料以成為表1至表4所記載之組成的方式進行稱重並均勻地混合。
其次,將已混合的原料投入鉑坩堝,依照玻璃組成的熔融難易度以電爐於1300℃至1600℃進行熔融2小時至24小時。之後,攪拌經熔融的玻璃進行均質化後將溫度降至1000℃至1450℃後澆鑄至模具,進行緩冷製作成毛坯玻璃。將獲得的毛坯玻璃以表1至表4所示之結晶化條件進行加熱來製作成結晶化玻璃。
實施例1至實施例38以及比較例1的結晶化玻璃之結晶相係判別自使用了X光繞射分析裝置(Bruker公司製造,D8 Discover)之X光繞射圖形中所呈現的波峰之角度。實施例1至實施例38的結晶化玻璃由於全部在相應於α-白矽石及/或α-白矽石固溶體的波峰圖案之位置見到主要波峰(強度最高且波峰面積最大的波峰),而判別為全部是α-白矽石及/或α-白矽石固溶體析出作為主結晶相。比較例1的結晶化玻璃沒有看到α-白矽石及α-白矽石固溶體的波峰。在比較例1確認到MgAl
2O
4、MgTi
2O
4的結晶相。
將製作好的結晶化玻璃進行切斷及磨削,進而以厚度成為10mm的方式進行對向平面平行研磨,來獲得結晶化玻璃基板。
針對結晶化玻璃實施以下的評價。將結果顯示於表1至表4。
(1)維克氏硬度
維克氏硬度係以下述方式得到的值來表示:使用相對面夾角為136°的鑽石四角錐壓頭在試驗面造出金字塔形狀的凹痕,將造出凹痕時的負荷除以由凹痕的長度所算出之表面積(mm
2)而得。使用島津製作所股份有限公司的微小維克氏硬度計(Micro-Vickers Hardness Tester)HMV-G21D,以試驗負荷100gf、保持時間10秒鐘來測定。
(2)著色度
利用分光光度計(日立先端科技(Hitachi High-Technologies)製造,U-4000型)來測定厚度10mm時包含反射損失的光線穿透率。求出穿透率成為5%之波長(λ5)與穿透率成為80%之波長(λ80)。
