Basic Info of Strontium Titanate

What is Strontium Titanate?

Strontium titanate has a high dielectric constant and is an important raw material for electronic ceramic powder. Its products have the advantages of low dielectric loss and good thermal stability, so it is widely used in the electronic industry.

The most typical method is the laboratory method provided by the “Research on New Methods of Synthesis of Strontium Titanate Powder” in the inorganic salt industry in 2002. This method uses titanium tetrachloride and strontium chloride as raw materials, ammonium carbonate and ammonia water as precipitants. , strontium titanate powder was synthesized by chemical co-precipitation method, and the effect of process conditions on product purity and strontium-titanium ratio was studied.

Strontium Titanate Uses

  1. In 1955, an artificial gemstone without a natural counterpart made by the National Reed Company of the United States by flame melting. Its chemical composition is srtio3. Equiaxed crystal system. colorless. Refractive index n=2.409. Dispersion 0.190. Relative density 5.13. Hardness 5~6. No cleavage, fractured conchoidal. No fluorescence under UV light. This artificial gemstone is often cut into an emerald shape and is a very good substitute for diamonds.
  2. To prepare a strontium titanate transistor with simple process and good stability.
    Using the substitution doping method, the use of laser molecular beam epitaxy, pulsed laser deposition, magnetron sputtering, electron beam evaporation or molecular beam epitaxy and other film forming methods, on single crystal substrates (such as SrTiO3, YSZ, LaAlO3, Nb:SrTiO3 etc.) to prepare n-type strontium titanate SrAxTi1-xO3 or Sr1-xLaxTiO3 thin film material, wherein A is Nb or Sb; prepare p-type strontium titanate SrBxTi1-xO3 thin film material, wherein B is In or Mn. All x values are in the range 0.005-0.5.
    A layer of p-type and a layer of n-type strontium titanate are epitaxially together, and the two layers of strontium titanate films with different conductivity types form a pn junction at the interface, and this pn junction constitutes a strontium titanate crystal. Diode; a layer of p-type strontium titanate, a layer of n-type and another layer of p-type are epitaxially together, these three layers of strontium titanate film form a pnp junction, and this p-np junction is A pnp strontium titanate triode is formed; a layer of n-type, a layer of p-type and another layer of n-type strontium titanate are epitaxially together, and the three layers of strontium titanate film form an npn junction , this npn junction constitutes an npn strontium titanate triode.
    The product transistor adopts a full epitaxy process, so the layer thickness and carrier concentration of each layer are easier to control than those of the silicon germanium transistor, and the junction surface is sharper, and the product has a high melting point and good stability, so Strontium titanate transistors will become a widely used electronic device, and can also be developed into strontium titanate integrated circuits.
  3. A preparation method for preparing an amorphous strontium titanate thin film device
    The method includes: spin-coating a bottom electrode solution on the surface of the substrate and then annealing to form a bottom electrode; spin-coating a strontium titanate solution on the surface of the bottom electrode and then baking to form a strontium acid film; annealing the strontium titanate film, forming an amorphous thin film; performing electron beam evaporation and sputtering on the surface of the amorphous thin film to form a top electrode to obtain an amorphous strontium titanate thin film device.

    The biggest innovation of the amorphous strontium titanate thin film device is that the main oxide thin film layer of the device is an amorphous thin film, and the preparation method is simple, the temperature requirement in the preparation process is low, it can be mass-produced, and the prepared The strontium titanate thin film device has good stability, fatigue resistance and can be used cyclically, and has a large on-off ratio.

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
