摘要： 57 A composition and method of making a high strength semi-crystalline ceramic material of the lithium, aluminum, silicate oxides system type. The composition is characterized by a relatively narrow range of lithium, aluminum, silicate and potassium oxides to form a base glass batch and is modified by including a novel proportional combination of the catalysts or modifiers comprising the components TiO 2 , ZrO 2 and Sn0 2 and including one or more additives taken from a group consisting of B 2 0 3 , MgO, Cr 2 0 3 , Ce0 2 , V 2 0 5 and Na 2 0 within specific percentage ranges.
The composition is formed and subjected to heat treatment within certain time and temperature steps to provide for the desired degree, size and type of crystalline formation which exhibits the desired physical, mechanical and chemical properties which include a superior resistance to high speed projectiles for armour applications.
