Corrosion resistance of NZP and aluminum titanate
… and corrosion resistance were evaluated. NZP (Ba<sub>1.25</sub>Zr₄P<sub>5.5</sub>Si<sub>.0.5</sub>0₂₄ and Ca<sub>0.5</sub> Sr<sub>O.5</sub>Zr₄P₆0₂₄) and aluminum titanate (AT) were exposed to a simulated diesel engine environment. The effects of thermal cycling from room temperature to …

Synthesis and characterization of ultralow thermal expansion NZP- type compounds
… thermal expansion materials, based on the NZP structure, have been developed and evaluated for future application in ceramic diesel engines which require exceptional thermal shock resistance. Twenty-four cation substitutions, with electron valence ranging from +1 to +5, were used to replace …

Two-dimensional quench propagation model for a three-dimensional "high-temperature" superconducting coil
… commonly refereed to as normal zone propagation(NZP). A reliable NZP model is necessary for designing protection systems because a quench may cause irreparable damage if a section of the winding is over-heated. This thesis develops a numerical NZP model for a three dimensional, dry-wound, BSSCO- …

Stability and quench protection of high-temperature superconductors
… speedy 2-D or even 3-D normal zone propagation (NZP) within its winding, aided by good thermally-diffusive turn-to-turn spacers.

Thermal expansion and thermal conductivity of (Ca<sub>1-x</sub>,Mg<sub>x</sub>)Zr₄(PO₄)₆ where x = 0.0-0.4
… = 0.0-0.4. CMZP is a member of the NaZr₂(PO₄)₃ (NZP) class of ceramics and is being investigated for heat engine applications. Linear thermal expansion was determined with a dual push rod dilatometer and axial thermal expansion by high temperature X-ray diffraction and least squares refinement. …
