锆宝石围棋子的制备方法
摘要：
一种锆宝石围棋子，属于棋类用具，其特征在于：锆宝石围棋子的截面图是由半径为R1圆弧形成的上凸面、下凸面和两边半径为R2的圆弧面组成的，下凸面是由三段半径为R3、R4和R3，其中，半径为R4的圆弧向上凸起，R1、R2、R3和R4两两相切形成锆宝石围棋子的截面图，锆宝石围棋子的立体结构是上述截面图绕中心轴线旋转180°形成的，锆宝石围棋子由氧化钇稳定氧化锆粉体经压制、烧成、抛光而制成。该方法制备的锆宝石围棋子强度高，韧性高，使用寿命长，手感好，适合工业化大生产。
摘要（英）：

The invention discloses a zirconium gem go-chess piece, belonging to chess utensils. The zirconium gem go-chess piece is characterized in that a sectional drawing of the zirconium gem go-chess piece consists of an upper convex surface formed by a circular arc with the radius of R, a lower convex surface as well as circular arc surfaces which are arranged at two sides of the zirconium gem go-chess piece and have the radius of R; the lower convex surface comprises three sections of radiuses R3, R4 and R3, wherein a circular arc with the radius of R4 is upwards convex; R1, R2, R3 and R4 are tangential two by two to form the sectional drawing of the zirconium gem go-chess piece; a three-dimensional structure of the zirconium gem go-chess piece is formed by rotating the sectional drawing to rotate around a central axis by 180 degrees; and the zirconium gem go-chess piece is formed by pressing, sintering and polishing yttrium oxide stabilized zirconium oxide powder. The zirconium gem go-chess piece produced by the method has the advantages of high strength, high tenacity, long service life, favorable hand feeling and suitability for industrial large-scale production.
