High-technology ceramics (HTCs) are a hot issue worldwide, with research programs focused primarily on better control of raw materials, particularly on purity, particle size, and distribution; cost effective processing into desired final shapes; and design of desired properties. The development of novel powder production and densification techniques to reduce brittleness, and the growing need for replacing strategic metallic materials has revived interest in ceramics, but their underlying physical and chemical properties will preclude their replacing metals. The future trend will be to alloy ceramic powders to give the best desired chemical compositions and particle sizes and distributions, to adapt and develop new powder consolidations techniques, and to change classical designs to reduce cracking and to exploit the properties of ceramics to their best advantage. 23 references, 6 figures, 3 tables.
