Description

【発明の詳細な説明】 産業上の利用分野 本発明は共溶融アルミナジルコニア研磨材に係る。
従来の技術 米国特許第３，８９１，４０８号は既知のアルミナ／ジ
ルコニア研磨材が殆んど有用ではなかった低圧および中
圧研磨に特に適当である共晶組成及び近共晶組成（３５
〜５０％ジルコニア）を有する共溶融アルミナジルコニ
ア研磨材を開示する。
本発明は米国特許第３，８９１，４０８号に開示された
研磨材の改良でアシ、この改良は研磨布紙製品の性能を
改良するのに特に有用であることが見い出された。
発明の概要 本発明は米国特許ｍ３，８９１，４０８号に開示された
共晶組成または近共晶組成のアルミナ／−）ルコニア研
磨材製品に係るが、Ｙ２Ｏ３として計算して酸化イツト
リウムを０．１〜２．０重量％含む点においてそうした
研磨材と区別される。この研磨材はたとえば、米国特許
第３，８９１，４０８号に教示されているよりにアーク
炉でアルミナ、ジルコニア、およびＹ２Ｏ３またはそれ
らのブレカーサ−を溶融してつくる。
この溶融は、少なくとも溶融製品をモニルドに流しこん
で急速に冷却すべき場合には、僅かに還元条件下で行い
、よって亜酸化物、炭化物、窒化物、炭窒化物、オキシ
ニトリド、またはいくつかの元素状金属のような還元生
成物が少量であるが認めうる量で存在するようにすると
とが好ましい。
こうして、この製品は明るい色または白つほい外観を有
するというよシも、認めうる金色の金属領域を時々伴っ
て黒色の外観を有する。このような部分的に還元された
材料の存在は、１０分の数置ｆｉ％の窒素および炭素の
存在、そして３％またはそれ以下の酸化による重量増加
によって示される。
この製品は溶融状態から急冷して、先行する特許第３，
８９１，４０８号に記載されているように微細な結晶構
造を作シだし、よって共晶コロニーの中心の平均−，ド
間隔が４，０００オングストロームより小さくすること
が不可欠である。
還元条件を確実にするために、炭素またはアルミニウム
またはジルコニウム金属のような容易に酸化される物質
を、溶融物を急冷モールドに流しこむ直前に添加するこ
とができる。
冷却後、製品をたとえばロールクラッシャーで破砕し、
篩にかけ、砥粒の有用な寸法部分に分別する。それから
砥粒はこの業界で公知のすべての慣用の仕方で予め作成
された可撓性基材に適用して研磨布紙製品を製造するこ
とができる。
Ｙ２Ｏ３の溶融物への添加の効果は単斜晶ジルコニアの
含有量を低減し、よって相変態（正方晶系から単斜晶系
へ）によるクラックを最小限化することにあると信じら
れる。その結果高い硬度が得られる。
