    • The invention relates to siliceous materials in the form of elements of aligned elongated individual crystals and more particularly to methods of forming such elements, said methods comprising providing a siliceous melt which will yield at the temperature of crystallization a primary crystalline phase which has a silicate chain structure, and drawing said melt, crystal nucleation having been induced, the rate of drawing being such as to cause continuous propagation of crystals of the said primary phase generally in the direction of drawing. The melt is drawn after crystal nucleation from an orifice, which can be directly or indirectly heated, of any desirable shape, such as circular, elongated or annular so as to result in the element being of cylindrical, sheet or tubular form or even of more complicated shape such as in cross-section to approximate to a turbine or compressor blade shape. Means may be provided to cause the element to disintegrate into units of a smaller number of aligned elongated crystals or even of single elongated crystals.
    • 本发明涉及以对准的细长单个晶体的元件形式的硅质材料,更具体地涉及形成这些元素的方法,所述方法包括提供硅质熔体,其将在结晶温度下产生具有硅酸盐链的主结晶相 结构和拉伸所述熔体,晶体成核已被诱导,拉伸速率通常使得所述主相的晶体在拉伸方向上连续传播。 熔体在晶体成核后从可以被直接或间接加热的孔形成为任何所需形状,例如圆形,细长或环形,从而导致元件为圆柱形,片状或管状形式,甚至更多 复杂的形状,例如横截面近似于涡轮机或压缩机叶片形状。 可以提供装置以使元件分解成更少数量的对齐细长晶体或甚至单个细长晶体的单元。
