Abstract

<abstract abstract-type="main" id="jace12619-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The formation of the Y_4.69(SiO₄)₃O apatite phase was observed in compositions targeted at the yttrium monosilicate and disilicate phases. Through the use of high‐temperature <italic>in situ</italic> X‐ray diffraction, the lattice parameters of the phase were characterized as a function of temperature, and thermal expansion coefficients were calculated. Phase fractions were assessed as a function of sintering temperature, and the apatite phase fraction increased with temperature.</p> </abstract>
