The materials consist of an agglomeration of one-dimensional (1-D)
nanostructures with random growth directions.
Statistical analysis of many SEM images reveals that the deposits at 900 º C and 970º C, respectively, have widths in the range of 100 nm-1 µm and 100 nm-7 µm.

The growth was conducted under influence of Ethane-1,2-diamine, the amine based enhancer in three different ratios (1:0.5, 1:1, 1:1.5).
The effect in three different ratios of precursor (Zinc Nitrate and HMTA) to the enhancer (Ethane 1-2 Diamine), the ratios 1:0.5, 1:1, 1:1.5 were studied.

Results and discussion
Fig. 1 shows the typical XRD pattern
of the as-synthesized product.
It is generally agreed that the SnO(g), which forms at the initial stage of oxidation of Sn (Sn(s) + 1/2O2(g) → SnO(g)), is metastable and decompose according to the reaction [14]: 2SnO(g) → SnO2(s) + Sn(l).

Abstract: Monotectic alloys are of great industrial importance because of their favorable tribological behavior.
Thus, studies concerning such alloys have deserved much attention in the last years [1-2].
A detailed partial phase diagram of the Al-Pb system is shown in Fig. 1.

However, the hardness of ceramic can be associated with greater abrasiveness against natural teeth, which lead to wear of the opposing teeth [1-3].
The porosity appears to be reduced on higher sintering temperature, which confirm the porosity percentage results of the SEM images that are 19,31% on 1110oC; 10,52% on 1120oC; 3,38% on 1130oC; 1,56% on 1140oC; and 1,22% on 1150oC respectively. 10µm (A1) (A) 10µm (B1) (B) 10µm (C1) (C) (D1) 10µm (D) (E) (E1) 10µm Fig. 1.
