Thermal analysis of zinc samples for the thermometric fixed point
On the basis of theoretical considerations and with the support of experimental results, it has been concluded that the melting range of an extremely pure (69 grade) zinc sample is not uniquely defined. The use of a determined conventional melting range in standard conditions is proposed in order to classify zinc samples on the basis of total impurity content. Some comparison data of four zinc samples for the thermometric fixed-point determination are given.
