This article describes the combined mixture of antimony and tantalum in SnO 2 varistors.
The results show that a moderate level of antimony can reduce the grain resistivity and …

Preparing halide perovskite films by solvent‐free, powder‐based processing approaches
currently attracts more and more attention. However, working solar cells employing dry …

Developing highly efficient semiconductor metal oxide (SMOX) sensors capable of accurate
and fast responses to environmental humidity is still a challenging task. In addition to a not …

In this research, full density, single phase microstructure (in the XRD and SEM detection
limits), and fine-grained SnO 2 varistors with an average grain size of 0.65 μm was acquired …

Pentavalent metals have been used as donors in tin dioxide, giving it varistor characteristics
when associated with densifiers such as CoO or MnO 2. However, attempts to obtain varistor …

It is shown that an addition of Sb 2 O 5 or Nb 2 O 5 (0.05–0.15 mol%) to the system SnO 2–
CoO–Cr 2 O 3–Bi 2 O 3 leads to the enhancement of grain growth. This effect is associated …

High-temperature solid phase sintering method was used to prepare high gradient SnO 2–
ZnO–Ta 2 O 5 based varistor ceramics doped with In 2 O 3 and Mn 2 O 3. We studied the …
