Japanese to English: Sintered Ceramic Body
Source text - Japanese β-リン酸三カルシュウム（以下 β-Ｃ３Ｐと略記する)は、人工骨の材料として有望であることからその合成および焼結法について研究が行なわれているが、機械的強度の面で十分な性能のものが得られていない。その原因のひとつは、β- Ｃ３Ｐが1180°Ｃ高温形のα-Ｃ３Ｐへ相転移し結晶密度が３.07から２.７７へ変化するに伴って容積の膨張が起こり、焼結体組織が弱化することにある。　従来はこの現象を避けて　β-Ｃ３Ｐの相転移温度（1180°C）以下の温度で加熱処理する方法がとられてきた。しかしリン酸ンカルシュウム粉末は、１２５０ °Ｃより低い温度では十分に焼結しないので、得られる焼結材料の強度に限界があった。以上のようにβ-リン酸ンカルシュウムの高強度焼結材料を製造するのに、それ自身の相転移の性質が根本的な障害になっている。	Translation - English As β-tricalcium phosphate (abbreviated as β-C3P hereafter) is a promising material for synthetic bones, many studies have been done on the synthesis and sintering method of this material. However, materials having adequate mechanical strength have not been obtained. One reason is that phase transition of β-C3P to a high temperature form of α-C3P occurs at 1180°C. Thus, the crystal density changes from 3.07 to 2.77 , which results in volume expansion and weakening of the sintered body structure. To circumvent this problem, heat treatment had been performed at below this phase transition temperature (1180°C) in conventional methods. However, as tricalcium phosphate powder does not completely sinter at a temperature below 1250°C, sintered materials produced by those conventional method showed only limited strengths. Thus the phase transition characteristic of β-tricalcium phosphate itself is the fundamental hindrance in producing its high strength sintered materials.
