High Temperature GlazeIn functional ceramics this term generally refers to glazes that mature at cone 8 and higher. At these temperatures natural minerals like feldspar, calcium carbonate, etc can be compounded to create glazes that will melt well without the need for powerful (and troublesome fluxes) like zinc oxide, boron or lead. Materials like Albany slip will melt unassisted to produce beautiful glossy glazes. In addition, high temperatures mean that less high expansion fluxes are needed and so it is much easier to create glazes that do not craze.Out Bound Links

Hot PressingHot pressing is a process used to fabricate ceramic parts (often from non-oxide powders like BIN, SiC or B4C). The process involves the simultaneous application of pressure and heat to a 'green' component or powder under a controlled atmosphere (depending on the material being processed). Since pressure is applied directly the shape of parts is limited to those that will release from the mold face along a single axis.Out Bound Links
