200426243 玖、發明說明: 【發明所屬之技術領域】 本發明係關於一種無機粉末的表面塗佈方法及使用該方 法所形成之無機粉末,特別是一種將一金屬氧化物均勻地沉積 於一無機粉末的方法,並且該無機粉末係應用於積層型陶瓷電 容器(Multi Layer Ceramic Capacitor, MLCC)内或是 用來作為經電池的活性物質。 【先前技術】 積層型陶瓷電容器通常包含有兩片金屬電極(例如鎳或銅) 以及一介於該等金屬電極之間的介電陶瓷層(例如鈦酸鋇)。 此外,由於積層型陶瓷電容器的體積小且電容量大,所以積層 型陶瓷電容器係廣泛地應用於電腦、手機以及其他電子產品 上0 由於銀纪合金可以在空氣中燒結,所以銀I巴合金係已被用 來作為金屬電極。不過,因為銀鈀合金電極的製造成本相當高 昂,所以鎳金屬已逐漸地取代銀把合金,不過鎳金屬通常必須 在低壓下燒結,以避免氧化。 圖一係為鈦酸鋇介電層100與鎳電極圖案200的製造示 意圖。 接下來將解釋習知鎳-積層型陶曼電容器的製造方法。如 圖一所示,首先,將鈦酸鋇粉末分散系塗佈於一基板(例如PET) 表面,以形成一鈦酸鋇粉末介電層(BaTi〇3 powder 7 200426243 dielectric layer)100。接著,利用網印的方式,將鎳粉 分散系塗佈於鈦酸鋇介電層100表面,以形成複數個鎳粉末 電極圖案(财 powder electrode layer pattern)2〇〇。 重複前述步驟數次,以形成多層的鈦酸鋇粉末介電層1〇〇及 鎳粉末電極圖案200。最後,沿著切割線3〇〇將前述之多層 結構切割分離,並利用燒結的方式,將鈦酸鋇粉末介電層1〇〇 及錄粉末電極圖案200燒結成鈦酸鋇介電層(BaTi〇3 mono-layer dielectric layer)及鎳電極圖案⑺土 mono layer electrode layer pattern),如此便完成 鎳-積層型陶瓷電容器的製作。 由於在燒結之前,鎳粉末電極圖案200内具有大量的有機 媒介’所以燒結前之鎳粉末電極圖案2〇0的排列密度 (packing density)較低。因此,當鈦酸鋇粉末介電層ι〇〇 及錄粉末電極圖案200經過燒結之後,鎳粉末電極圖案2〇〇 的收縮程度會大於鈦酸鋇粉末介電層100。 此外,鎳金屬粉末的燒結溫度大約是6〇0°c,而鈦酸鋇粉 末的燒結溫度大約是125〇〜13〇〇艽,所以鎳金屬粉末在 400〜500°C之間便會開始收縮,然而鈦酸鋇粉末則必須在 1100C以上才會開始收縮。因此,在鈦酸鋇粉末介電層1〇〇 及鎳粉末電極圖案200的燒結過程中,當溫度到達400〜5 00 C時’鎳金屬粉末已經開始在收縮,然而鈦酸鋇粉末卻沒有任 何收縮的跡象。 由於鈦酸鋇粉末介電層100及鎳粉末電極圖案200的燒 結溫度以及收縮率(shrinkage rate)均不相同,所以燒結 後之欽酸鋇粉末介電層1〇〇及鎳粉末電極圖案2〇〇之間會有 很強的收縮應力(c〇ntracti〇n s t r e s s )存在’該收縮應力 ’4提升冑歡間的接觸 酉夂鋇粉末來填_粉之_ 5案心離。例如’利用鈦 的收縮率,然而由於鈦酸鋇於東沛降低鎳粉末電極圖案200 所-粉末電極圖案;縮率 此外,另一個方法是利用表面且 成錦粉末電_案2⑽,由於表氧化物之錄粉來形 縮起始溫㈣接近滅_//的=氧化物之錄粉的收 粉表面的金屬氧化*二;\^而言,用來覆蓋於錄 Γΐ盖=化鈦(Ti〇2)、鈦酸鋇以及驗土金屬氧化物二 th 、’利6268054所揭露,喷麗式熱分解法(Spray thermal decompositi〇n)與溶膠凝膠法(s〇i_gu =tlng process)等方法均可用來將金屬氧化物塗佈於錄 粉表面。 在喷灑式熱分解法中,鎳粉係先與熱分解化合物形成一溶 液,然後將該溶液喷灑入一加熱管中,此時該熱分解化合物便 會於該加熱官中產生分解,並於鎳粉表面形成金屬氧化物。然 而,此法不僅會在鎳粉表面形成金屬氧化物,也會在鎳粉内部 形成金屬氧化物,因而造成原料浪費,益提高製程成本。 另一方面,溶膠凝膠法係先將一欲鍍物質溶解於水而形成 一水溶液,然後再將鎳粉加入該水溶液中,隨後經由溶膠凝膠 反應,便可利用物理與化學的方式而將該欲鍍物質形成於鎳粉 200426243 表面。之後,鍍好之鎳粉會經過過濾、乾燥以及加熱等步驟, 以使鎳粉表面之物質轉變成結晶態。一般而言,此法不僅可製 作一結構穩定之鎳粉,更可有效地大量生產。 請參考圖二,圖二係為利用溶膠凝膠法來將二氧化鈦塗佈 於鎳物表面之方法流程圖。如圖二所示,在步驟(1)中,先將 鎳粉加入水中,並使鎳粉分散於水中而形成一鎳的膠態溶液 (aqueous Ni p〇wder slurry),然後再將一四氣化鈦 jTxci4)水溶液與一氫氧化氨(NH〇H4)水溶液加入該鎳的膠 態溶液中並攪拌之,其中,四氯化鈦係會與氫氧根離子反應而 產生氫氧化鈦(Ti (〇H) x)沉澱物,而氫氧根離子係經由以下的 酸驗反應所產生: nh4oh — NH4+ + 〇Η· 隨後,氫氧化鈦係沉積並覆蓋於鎳粉的表面(步驟(3))。 之後,利用醇溶液來清洗表面具有氫氧化鈦之鎳粉(步驟 (5)),以移除不純物並將氫氧化鈦的氫氧基團(hydr〇xy group)轉變成烧氧基團(alk〇Xy gr〇up),以避免氫氧化鈦 的氫氧基團在後續的乾燥過程中產生縮合反應 (condensation reaction),而導致鎳粉產生團塊化現象 (agglomeration)。然後,對清洗後之鎳粉進行一乾燥製程 (步驟(7))。最後,當乾燥製程進行完成之後,便進行一熱處 理製程於乾燥後之鎳粉上,並且該熱處理製程係於一氧化環境 (exudative atmosphere)下,利用 4〇(Γ(>5〇〇0(:之高溫 來加熱乾燥後之_,在該熱處理製程中,氫氧化鈦係轉換成 二氧化鈦’如此-來便可使二氧化鈦塗佈於錄粉表面。 10 200426243 ⑴由於鎳粉表面具有氫氧化鈇,所以不同鎳顆粒表面上 的氫氧化鈦便可能產生縮合反應,而產生Ti_〇_Ti鍵結,進 而使部分的鎳顆粒之間產生團塊化現象。 (2)由於習知的溶膠凝膠法係利用水作為分散介質,水經 過酸驗反應會在短__產生大量的氫氧根離子,並且當四 氯化鈦與大量的氫氧根離子反應之後,便會於短時間内產生大 1的氫氧化鈦沉澱物,如此一來,部 水溶液中聚集成塊(Cluster)而、/欽儿物便在 ,^ φ )而 >又有沉積在鎳顆粒的表面 外’進而使某二鎳顆粒的表面因為沒有鑛有氫氧化鈦而裸露於 而且部分錄顆粒的表面因為沒有 &〆 使氫氧化鈦結晶成二氧化鈦結晶化鈦而裸露於外,此外,在 仍然存在,而且當麟處理進^理触巾,氫氧化鈦的凝結塊 更會隨著增加。 細的越久,氫氧化鈦的凝結塊的凝聚力
1PG 、 谷膠凝膠法所制+ ^ 陶瓷電容器所需之鎳電極, 斤I成之鎳粉來製作積層型 肘印面臨下列問題·· U)由於溶膠凝膠法所製 化之鎳粉係具有較大的表面 螺粉會有團塊化現象,團塊 來製作鎳電極,將會降低鎳極::因此若利用團塊化之鎳粉 電極在積層型陶瓷電容器之妗妙制厚度平整度,進而會增加鎳 凡、、、口襄程中產生斷線的情形。 (2)由於在溶膠凝膠法中, 刀鎳顆粒的表面因為沒有鍍 11 200426243 有氫氧化鈦而裸露於外,所以鈦酸鋇粉末與溶膠凝膠法所製成 之鎳粉的收縮溫度的差距仍然很大,因而容易造成鈦酸鋇介電 層及鎳電極圖案的分離。 由上可知,利用習知溶膠凝膠法所製成之鎳粉來製作鎳 電極,將會降低積層型陶瓷電容器的品質並提高失效率 (failure rate ),因此,如何將金屬氧化物均勻地沉積於 鎳粉表面而且不會產生團塊化現象,以提升積層型陶瓷電容器 的品質,便是一相當重要之課題。相同地,對於高效能之鋰電 池而言,如何將金屬氧化物均勻地沉積於鎳粉表面而且不會產 生團塊化現象,也是一相當重要之課題。 【發明内容】 因此,本發明的目的之一是提供一種無機粉末的表面塗佈 方法,以避免無機粉末產生團塊化現象以及避免金屬氧化物凝 聚成塊。 此外,本發明的另一目的是提供一種表面具有金屬氧化物 之無機粉末,其中該無機粉末表面之金屬氧化物係具有一均勻 之厚度,並且該無機粉末係不會產生團塊化現象,而且該金屬 氧化物亦不會凝聚成塊。 依據本發明之目的,本發明的較佳實施例係提供一種無機 粉末的表面塗佈方法,該方法包含有: 提供一醇溶性金屬鹽之醇類溶液與一胺類化合物之醇類 溶液;以及 將一無機粉末與水加入該醇溶性金屬鹽之醇類溶液與該 12 200426243 胺類化合物之醇類溶液之内並 形成之一金屬氯氧化物塗饰“二將^ 依據本發明之另一目的, 表面鑛有金屬氧化物之無^明的另-實施例係提供一種 粒均係分離而且沒絲結成^ 且該無機粉末内之各個顆 鍍在該無機粉末内之各個顆粒b外’該金屬氧化物係均勻地 或其=末本發明之無機粉末係包含有金屬粉末、金屬氧化物 團塊化現象,而屬氧化物的無機粉末係不會產生 =明:製成之嶋製作錄電極,不僅可提升=陶二 為的口Π質’更可增加積層型陶£電容器的良率。 Μ電合 :實施方式】 β月參考圖四,W四係為本發明之製造—表面具有金屬氧化物之無機, 粉末的方法流程圖。如圖四所示,以下將說明本發明之無機粉末^表 面塗佈方法及使用該方法所形成之無機粉末。 η 夂Μ (1)無機粉末膠態溶液(inorganic powder Slurry)的準備程 序(步驟1) ^ 在習知的溶膠-凝膠塗佈方法中,水係用來作為無機粉末膠態溶 液的分散介質(dispersion medium),不過在本發明中,醇類溶液 (alcohol)係用來作為無機粉末膠態溶液的分散介質。此外,本發明 13 200426243 所使用之無機粉末可以是粉末狀 態 態 /或散於醇類溶液之膠體狀 並且,本發明所使用之無機粉末係選自於鎳▼、’ 一"八之族群,此外,本發明 太/介,〜、‘…穴跟岍 (响)、氧化錯™、鈦氧化欽 (ΑΙ·2〇3 ) 氧化二銘 二氧化矽(Si〇2)、氧化釔(γ2〇) 三猛(Μη3〇4)、二氧化 乳化f_)、四氧化 組成之族群。 乳化鎳_)、與氧化鋅(Zn〇)所 (2)無機粉末的塗佈方法(步驟3) ίί水=無=末的膠態醇溶液與—醇溶性金屬鹽的醇類溶液、微 _化合物的醇類溶液相混合並_之。並且,前述之 二;mi自於醇溶性金屬鹽的醇類溶液或是由外加人疏 狀化較赋,醇雜金屬雜可與氫氧根 離子反應而沉澱為金屬氫氧化物。 • compound + h20 ^ Amine compound ~H+ + 〇h~ 、因此,金屬氫氧化物便可沉積於無機粉末之表面(步驟y。當醇 類浴液觀來作為無機粉末、金屬鹽與胺類化合物的分散介質(或溶劑) 時’由於醇類溶液之氫氧根離子的生成量較少,因而可減少無機粉末 在下,之乾燥製程中發生團塊化現象。其中,醇類溶液的種類並不限 定’最好是具有1至5個氫氧基團之醇類化合物,並且在室溫下是液 悲為佳,例如,C1~C7脂肪單醇化合物(cl〜c7 aliphatic㈣⑽一心 compound)、C6〜C9方香單醇化合物(eg〜c9 aromatic mono-ol compound)、C4〜C7 脂環單醇化合物(c4〜c7 alicyclic mono-〇l compound)、C3〜C7 雜環單醇化合物(c3〜c7 heterocyclic m〇no-ol compound)、C2〜C7 脂肪雙醇化合物(C2〜C7 aliphatic di-ol compound)、或 C2〜C7 脂肪三醇化合物(C2-C7 aliphatic tri-ol compound) ° 14 200426243 在本發明中,當醇類溶液的pH值增加,金屬氣氧化 屬鹽沉澱出的速率便合降伋。^ 知攸Sti谷性金 《錢日降低。—般而目,紐反應射分為均質成核 (―咖s nucleati〇n)與非均質成核加〜。卿貝: 騰叫兩種,當醇類溶液的邱值快速增加,金屬氫氧化物的 kΘ lx生在/合液中而不是在無機粉末的表面,因此,金屬氫氧化 物會在溶液巾軸大雛,而織粉柄表關沒有塗佈雜何物質。 相反地’當醇類溶液的pH值緩慢地增加,金屬氣氧化物的沉殿反· 應便會傾向於非均質成核,在此種情形下,金屬氫氧化物的成核作用參 通常會發生在無機粉末的表面,如此一來,便可將金屬氫氧化物沉積 於無機粉末的表面。同時,由於胺類化合物會與水產生酸鹼反應,並 且由於該酸鹼反應係進行於醇類溶液中,所以氫氧根離子會被緩慢地 釋放出來,以使溶液内的pH值可以緩慢地增加。如此一來,由於溶液 内的pH值係緩慢地增加,經由非均質成核反應所生成的金屬氫氧化物 大多會沉積在無機粉末的表面,如此便可將金屬氫氧化物塗佈於無機 粉末的表面。 本發明所使用之胺類化合物可以是一級胺(primary amine,脅 RNH2)、二級胺(secondary amine, R2NH)、或三級胺(tertiary amine, R3NH)。此外,本發明所使用之胺類化合物亦可以單胺化合 、 物(mono amine compound)或雙胺4匕合物(diamine compound)。 另外,本發明所使用之胺類化合物也可以是脂肪胺化合物 (aliphatic amine compound)或芳香胺化合物(aromatic amine compound)。舉例而言,本發明之胺類化合物可以是曱基胺 (methyl amine)、二曱基胺(di-methyl amine)、三曱基胺 (tri-methyl amine)、乙基胺(ethyl amine)、二乙胺(di-ethyl amine)、三乙胺(tri-ethyl amine)、正丙胺(n-propyl 15 200426243 amine)、異丙胺(is〇一 propyl amine )、正 丁胺(n 一 butyl amine)、第二丁胺(sec-butyl amine)、異丁胺 (iso-butylamine)、第二丁胺(tert-butylamine)、環己胺 (cyclohexylamine)、苯甲胺(benzylamine) 、α-苯基乙月安 (α-phenylethylamine) 、 β-苯 基乙胺 (β-phenylethylamine)、乙二胺(ethylenediamine)、丁二胺 (tetramethylenediamine) 、 己二胺 (hexamethylenediamine)、笨胺(aniline)、甲苯胺 (methylaniline)、二甲基苯胺(dimethylaniline)、二笨胺 (diphenylamine)、三苯基胺(triphenylamine)、鄰-曱苯胺· (〇-t〇luidine)、間-甲苯胺(m-toluidine)、對-曱苯胺_ (p-toluidine)、鄰-甲氧苯胺(〇-anisidine)、間-甲氧苯胺 (m-anisidine)、對-甲氧苯胺(p-anisidine)、鄰-氯苯胺 (〇-chl〇r〇aniline)、間-氣苯胺(m-chloroaniline)、對-氯苯 胺(p-chl〇r〇aniline)、鄰-漠苯胺(〇-bromoaniline)、間-淳 苯胺(m-bromoaniline)、對-漠苯胺(p-bromoaniline)、鄰-硝 基苯胺(◦-nitroaniline)、間-硝基苯胺(m-nitr〇aniline)、對 -硝基苯胺(p-nitroaniline) 、2,4,5-三石肖基苯胺 (2,4,5-trinitroaniline) 、 2,4,6-三硝基苯胺
