Abstract

We analysed thermal (20°-1000•Ž) phase changes of the substrates of

INFLUENCE OF TEMPERATURE (20^o-1000^oC) ON THE PHASE CHANGES IN Li₂CO₃ - MgHPO₄&bull;3H₂O SYSTEM

“…Preparation of the substrates and their binary mixtures: Substrates (1,11) were used as supplied (TABLE 1). Each compound was grounded, sieved, and binary mixtures were prepared with percentage molar ratios of 90% to 10% as described by Umbreit 7 . Preparation of sinters at 500°C and 1000°C: Substrates and binary mixtures were heated in melting pots at 500°C and 1000°C for 1 h as described by Umbreit 7 .…”

“…Apparatus and analytical procedure: Differential Thermal Analysis was performed using Derivatograph Q-1500D as reported by Umbreit 7 . IR analysis was carried out using tablets of potassium bromide and Carl Zeiss Jena spectrophotometer.…”

“…IR analysis was carried out using tablets of potassium bromide and Carl Zeiss Jena spectrophotometer. WAXS radiography analysis was performed as described by Umbreit 7 .…”
