Influence of low-temperature reaction time on morphology and phase composition of short calcium phosphate whiskers [PDF]

open access: yesProcessing and Application of Ceramics, 2019
The present work shows the results of the synthesis of multiphasic calcium phosphate whiskers from a mixture of biphasic calcium phosphate (β-tricalcium phosphate (β-TCP) and calcium pyrophosphate (CPP)) in the hydrogen peroxide solution-mediated process

Effect of impurities and sintering temperature on properties of MgO-CaZrO3 ceramic [PDF]

open access: yes, 2013
CaZrO3 -MgO ceramics are useful as refractories in kilns for the cement production. One method of manufacture of such ceramics is by sintering from m-ZrO2 and dolomite MgCa(CO3 )2 mixtures. In this work electrofused m-ZrO2 grains (fraction

Study of Impact Characteristics of ZrO2 Ceramic Composite Projectiles on Ceramic Composite Armor [PDF]

open access: yesMaterials, 2022
Exploring new armor-piercing materials is crucial for improving the penetrative ability of projectiles. Based on the process of in situ solidification injection molding through ceramic dispersant hydrolytic degradation, a ZrO2 ceramic material suitable for use as the tip of a 12.7 mm kinetic energy (KE) projectile was prepared. The ZrO2 ceramic tip can

An attempt to obtain Bi_{4}Ti_{3}O_{12}-PVC textured ceramics-polymer composites

open access: yes, 2013
Bi_{4}Ti_{3}O_{12}-PVC composites were fabricated. Ceramics powders of bismuth titanate were prepared by the sol-gel method using bismuth nitrate pentahydrate Bi(NO_{3})_{3} \cdot 5H_{2}O and tetrabutyl titanate Ti(CH_{3}(CH_{2})_{3}O)_{4} as precursors.

A meta-analysis of the mechanical properties of ice-templated ceramics and metals [PDF]

open access: yes, 2015
Ice templating, also known as freeze casting, is a popular shaping route for macroporous materials. Over the past 15 years, it has been widely applied to various classes of materials, and in particular ceramics.
