本発明は高強度、高靭性のジルコニア質セラミックス印
鑑に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a zirconia ceramic stamp with high strength and high toughness.
従来印鑑は木、水晶、水牛の牙、象牙等の自然物で製造
されているが、これらの材質で製造した印鑑は長期使用
によって摩耗したシ、あるいは欠損したシして刻印が不
鮮明になったシ、または刻印の欠落と事故があった。Traditionally, seals are made from natural materials such as wood, crystal, buffalo tusk, and ivory, but seals made from these materials tend to wear out or become damaged due to long-term use, making the stamp unclear. , or there were missing markings and accidents.
また、プラスチックで製造した印鑑が知られているが、
この印鑑は軟質であシ、長期使用によって摩耗し、刻印
が不鮮明となシ、また火災等によって焼失してしまうと
いうものであった。 ゛そこで近年は不燃性、耐摩
耗性を有するアルミナ質セラミックスの印鑑が考えられ
ている。しかしながらアルミナ質セラミックスの印鑑に
おいて。Seals made of plastic are also known,
These seals were soft and would wear out with long-term use, making the stamps unclear, and could be destroyed by fire. Therefore, in recent years, seals made of alumina ceramics, which are nonflammable and wear resistant, have been considered. However, in alumina ceramic stamps.
も、何かの原因によシ、例えば落すことによυ部分的に
欠けを生じ、刻印が欠損したシ、あるいは割れ等の問題
があった。However, due to some reason, for example, if the item was dropped, it would become partially chipped, the engraving would be missing, or it would crack.
本発明者は上記実情に鑑み、検討をした結果、ジルコニ
アセラミックス特に部分安定化ジルコニアセラミックス
が高強度であシ、かつ高靭性であることを見出したもの
で、ジルコニアセラミックスの素地に名称等の刻印を施
こし、次にこれを焼成することによってジルコニアセラ
ミックス印鑑が簡単に得られる・ものである。In view of the above-mentioned circumstances, the inventors of the present invention have conducted studies and found that zirconia ceramics, particularly partially stabilized zirconia ceramics, have high strength and toughness. A zirconia ceramic seal can be easily obtained by applying this and then firing it.
本発明は部分安定化ジルコニア質のセラミックス印鑑で
あ）、ジルコニアの安定化剤としては、Ｙ２Ｏ３、Ｃａ
Ｏ、ＭｇＯ等が用いられるが、Ｙ２Ｏ３で部分安定化さ
れたジルコニアセラミックスが特に強度、靭性に優れて
いるものである。The present invention is a partially stabilized zirconia ceramic seal), and the zirconia stabilizers include Y2O3, Ca
Although O, MgO, etc. are used, zirconia ceramics partially stabilized with Y2O3 is particularly excellent in strength and toughness.
この部分安定化ジルコニア質セラミックスは素地は軟ら
かくて刻印がし易く、焼成すると高強度、高靭性になる
。The base of this partially stabilized zirconia ceramic is soft and easy to engrave, and when fired it becomes high strength and toughness.
本発明のジルコニア質セラミックス印鑑Ｋｌいては、立
方晶、正方晶及び単斜晶の３相からなシ、かつ立方晶が
５〜６５重量％、正方晶が３０〜９０重量％、単斜晶が
５〜２０重量％であるものが高強度、高靭性の点で好ま
しい。さらに、耐熱性を考えた場合に不純物総量が０．
８５重量％以下であることが望ましいものである。しか
し、色調の点から不純物としてＦｅ２Ｏ３を０．１〜０
．０２重量−程度含有することによシ、よシ象牙の様な
色あいとなシ好ましい。The zirconia ceramic seal Kl of the present invention is composed of three phases: cubic, tetragonal and monoclinic, and contains 5 to 65% by weight of cubic crystals, 30 to 90% by weight of tetragonal crystals, and 30 to 90% by weight of monoclinic crystals. A content of 5 to 20% by weight is preferred in terms of high strength and high toughness. Furthermore, when considering heat resistance, the total amount of impurities is 0.
It is desirable that the content be 85% by weight or less. However, from the viewpoint of color tone, Fe2O3 is added as an impurity from 0.1 to 0.
．． It is preferable to contain about 0.02 weight percent, and it is preferable to obtain a more ivory-like color.
以下本発明の実施例について説明する。 Examples of the present invention will be described below.
実施例
平均粒径０．９μｍで純度９９．８％の単斜晶ジルコニ

合し造粒した後、２．０トン／ｃｍ ２の条件で加圧成
形した。つづいて名称を刻印した。Example Monoclinic zirconia powder with an average particle size of 0.9 μm and a purity of 99.8%, an average particle size of 0.9 μm obtained by coprecipitation method,
A zirconia compound powder having a purity of 99.9 Ls was mixed so that the final yttria content was 2.0 mol %. Next, polyvinyl alcohol was mixed into the mixed powder as a binder and granulated, followed by pressure molding at 2.0 tons/cm 2 . Next, I engraved the name.
この成形した印鑑を大気中において２時間焼成した後冷
却し、ジルコニア質セラミックス印鑑を得た。This molded seal was fired in the atmosphere for 2 hours and then cooled to obtain a zirconia ceramic seal.
得られたジルコニア質セラミックス印鑑は落しても強度
は強く、しかも曲げ強さをしらべた結果１０２ ｋｌ／
絽２であった。The obtained zirconia ceramic seal is strong even if it is dropped, and the bending strength was 102 kl/
It was 紽2.
また、このジルコニア質セラミックス印鑑にＦｅ２Ｏ３
を０．０５重量％を加えたものは、象牙のような色あい
Ｋなった。In addition, Fe2O3 is added to this zirconia ceramic seal.
When 0.05% by weight was added, the color K became ivory-like.
本発明は印鑑の素地が１．３３四方のものが、焼成後の
印鑑は１３四方になった。したがって、名称を刻印する
場合、大変刻印し易い印鑑であるとともに素地は軟らか
で刻印はし易いものである。In the present invention, the base of the stamp is 1.33 square, but the stamp after firing is 13 square. Therefore, when engraving a name, the seal is very easy to engrave, and the base material is soft and easy to engrave.
またシャープなエッヂを保持するため、非常にシャープ
な印字が刻印することができ、半永久的に使用できる。It also maintains sharp edges, allowing for extremely sharp markings and semi-permanent use.
なお、高強度でかつ高靭性でアシ、曲げ強度が１０２
＊ｔ／ｙｍ”であシ、従来使用している水晶、水牛。In addition, it has high strength and high toughness, with a bending strength of 102
*T/ym" Ash, conventionally used crystal, water buffalo.
象牙の印鑑よシ強度は強く、かつ刻印する時は素地であ
るので軟らかい印鑑である。It is stronger than an ivory seal, but it is soft when engraved on the base material.
