Abstract-The present column lists commerctally available magnesmm and tttamum alloy reference matenals Pure metal, vanous alloys, ores and settmg-up samples have been constdered. Included are three tables that provtde an easy-to-use survey The followmg information IS covered: the name of the matenal, the sample code, the producer, the reference to certdication, the names and addresses of the suppliers from whom the reference matenal may be obtained, and spectfic remarks

EMISSION and X-ray fluorescence spectrometers have become essential parts of most industrial analytical laboratories. The principal reason for their extensive use are the speed with which determinations can be performed as well as the high accuracy and sensitivity. Since these spectroscopic methods of analysis are based essentially on comparison techniques, the spectrometers are dependent upon calibration samples. Reference materials (RM) of accurately known composition are therefore of prime importance. They must be similar to the material to be analysed and cover the concentration range most generally encountered in practice. It is obvious that a large number of RMs is necessary.

In previous papers [I-3], non-ferrous metallurgical reference materials (Al, Cu and Zn) have been tabulated. The present instalment concerns two “light” metal materials: magnesium and titanium, and their alloys.

Trace elements in metallurgical materials are of considerable importance as many minor constituents affect or even control the desired properties of the final product and the applications for which it can be used. Some metallic impurities may be beneficial, some may exert a rather negative effect. Rigorous control of the level of these elements within tolerable limits is of major importance.

Addition of selected metals (W, Ta, Nb, MO, V, Cr, etc.) to magnesium metal and its alloys improve oxidation and corrosion resistance. Beryllium is important in magnesium alloys because of ignition prevention properties.

Most non-ferrous metals and alloys contain measurable amounts (10-5000 pg/g) of oxygen, nitrogen and hydrogen that have been introduced through processing. The presence of these gaseous impurities results in profound effects on the physical, mechanical and electrical properties of the reactive metals such as titanium. The accurate determination of these impurities is a serious problem for the gases-in-metals analyst.

Titanium metal is of importance in the aeronautical industry and for a number of applications where its low specific weight, its high corrosion resistance and its high melting point justify its use. The production of very pure titanium metal requires as complete an evaluation as possible of its metallic impurity concentration.

Titanium dioxide is a widely used pigment. The presence of trace elements (Cr, V) has a negative effect on the quality of the pigment, while the addition of A&O3 results in a markedly decreased corrosion rate. In the pharmaceutical industry, the concentration of poisonous elements (such as Pb, Sb) in titania has to be below a specified limit.

For the preparation of this issue, inquiries were addressed to various certifying institutions, producers, commercial firms and official distributors. Only agencies who replied to our request for information at the time of writing are mentioned here.

Reference samples are currently available in a variety of forms: chips; disks; pins. Generally, analysis certificates are supplied with each RM that specify the chemical content, the co-operating laboratories, the analytical methods used, recommendations, advice for the use of the material, etc.

The presentation of the present survey follows the general style we have adopted in our previous instalments of the column.

Three tables have been prepared to provide, in a convenient way, a maximum of necessary information to the user of reference samples, and to make it easier for him to find what he is looking for.

In Table 1, magnesium and titanium materials have been grouped into four principal classifications

1. Pure metal 2. Various alloys 3. Ores 4. Setting-up samples.

The table is organized as follows.

(1) (2)

(3)

(4)

The name of the material is given in the first column.

The sample code, i.e. the usual abbreviations given by the originator, is shown in column two.

The acronym of the producer is stated in the third column.

References of certification, reports, catalogues or preliminary information are identified by a number preceded by the letter R. The number in the relevant column refers to the list presented in Table 2.

The supplier from whom the material may be obtained is identified in a similar manner (using S as the first letter). The name and addresses of the suppliers of the reference materials mentioned in Table 1 are given in Table 3. In this manner, readers are able to obtain further information directly from such sources (catalogue, price list, quantity of the supply, details of the purchase procedure, etc.).

Specific remarks that may assist the reader in his choice of samples are indicated in the last column.

In preparing the paper, unfortunate oversights might have occurred and many materials possibly used as standards may have been omitted for whatever reasons. In such cases we apologize to the readers. We will ask them insistently to inform us of their remarks and suggestions so that we can take these into account in the future, and improve the usefulness of this column. Producers and suppliers of reference materials are invited to send pertinent information about their products and services to the address given above.
