Task Group
Chairman: M. Kizilyalli (deceased)

Members: J.O. Carlsson, A.B. Ellis, R. Kniep, H. Mandal, G.V. Subba Rao, U.V. Varadaraju, and A. Yilmaz

Remarks: previously 230/29/95

Completion Date: 2006 - project abandoned

Objective:
The objective is to provide tested experiments that will allow experiments illustrating solid state and materials chemistry to be introduced into the chemistry curriculum and experiments illustrating chemical aspects to be introduced into the materials science curriculum.

Description:
The experiments to be prepared can be classified into 3 categories:

to be used in junior undergraduate laboratories (2nd and 3rd year)
to be used in senior undergraduate laboratories (4th year elective courses such as "Introduction to Solid State Chemistry and Inorganic Materials" and "Inorganic Structural Chemistry"
to be used for the senior undergraduate students (4th year) as projects and for master students as laboratory courses; these could be advanced and expensive since few students will use them.

Since in recent years the development in high technological materials is a very important issue, this type of scientific document will be very useful in the advancement of preparing new compounds.

Two sets of laboratory experiments in the field of solid state chemistry edited by Prof Dr. Lars Kihlborg were submitted to IUPAC commission II-3.
First Set:

Preparation and characterisation of barium titanate (BTO) and BTO 'posistors'
Synthesis of ferroelectric BaTiO₃ via sol-gel route
Fabrication of thin film CdSe photoelectrochemical solar cell and measurement of its efficiency
Synthesis and study of the high-Tc superconductor YBa₂Cu₃O_7-d.
Synthesis of a '123'-superconductor
Ionic conductivity in glass
Synthesis of luminescent materials
Synthesis of ferrimagnetic BaFe₁₂O₁₉
Synthesis of X-zeolite

Second Set:

Synthesis and properties of LaCoO₃ and La_0.6Sr_0.4CoO₃
Preparation and characterisation of an intermetallic compound, V3Si
Synthesis and crystal growth of MoO₂ and characterisation
Synthesis and magnetic characterisation of a hard magnetic material, BaFe₁₂O₁₉
Synthesis and intercalation studies on the layered transition metal dichalcogenides, 2H-TaS₂ and 2H-MoSe₂
Synthesis and characterisation of a metal-cluster compound, Cu₂Mo₆S₈

Some experiments have been tested in the laboratories of Middle East Technical University, Chemistry Department and were found to be feasible and applicable. Some of them can be useful only in a well-equipped solid-state laboratory. Several experiments were added to the list developed in the Middle East Technical University Chemistry Department.
These are:

Synthesis and Characterization of Lanthanide Phosphates
Synthesis of Characterization of Tetracalcium Phosphate, Ca₄P₂O₉, A Dental Cement
Preparation of Gadolinium Tetraphosphate, Gd₂P₄O₁₃, and a Study of its Structure by XRD and IR Methods
Preparation of Copper Iron Sulfides by Solid-Gas Reactions
Synthesis, Characterization and Conducting Properties of YBa₂Cu₃S_6-x
Synthesis of Sodium Dichromate, Na₂Cr₂O₇, and Sodium Chromate, Na₂CrO₄
Preparation of YBa₂Cu₃O_7-x by Using Citrate Synthesis

This document is going to be ready when testing of the experiments will be done by another laboratory. The topic would be broadened considering the following fields in a systematic way:

Synthesis of solids by solid state, solution, hydrothermal or sol - gel methods.
Characterization using different Instrumental and chemical methods.
Determination of magnetic, electrical, optical, thermal and mechanical properties.

This project was presented at a poster session at the IUPAC Congress/GA July 2001

The process has been shown to work so those projects will build on and greatly expand and enhance the earlier work.
