Is there any material with higher temperature performance than graphite?

U.S. refiners forecast strong first-quarter earnings as margins on gasoline and diesel sales improved, refining capacity fell sharply and crude supplies tightened due to the Russia-Ukraine war.

Global refining capacity has declined amid the coronavirus pandemic, with several less profitable refineries closing in the past two years. However, global fuel demand has rebounded to near pre-pandemic levels, boosting the profits of facilities still operating.  

Seven U.S. independent refiners are expected to earn 61 cents a share, compared with a loss of $1.32 in the first quarter of 2021, according to Refinitiv's IBES.  

By 2022, gasoline and distillate sodium silicate.

Is there any material with higher temperature performance than graphite?

Boron nitride, which is a little expensive, can be bought as a ready made crucible.

Tungsten is expensive and can be processed into various shapes. It does not react with oxide melt and is not resistant to oxidation.

Zirconium boride and titanium boride have super melting points, but it is difficult to obtain dense blocks.

Beryllium oxide is very expensive and toxic.

Magnesium oxide, which is a little cheaper, does not react with metals.

How to remove titanium diboride coating on stainless steel after vacuum plating

It can be sandblasted with glass shot water,

As titanium diboride is acid resistant, it can be tested with high concentration caustic soda solution

However, it is estimated that the effect of the above two methods will not be very good

Because the chemical properties of titanium diboride are relatively stable and the hardness is very high.

If the coating is not very thick, the sandblasting effect is better.

Material properties of titanium diboride

Coefficient of thermal expansion 8.1 × 10-6m/m.k

Thermal conductivity/

Resistivity 14.4 μ Ω.cm

Oxidation resistance temperature (in air) ℃

Introduction of titanium diboride

Titanium diboride powder is gray or gray black, with hexagonal (AlB2) crystal structure. Its melting point is ℃ and it has high hardness. The oxidation resistance temperature of titanium diboride in air can reach ℃, and it is stable in HCl and HF acid. Titanium diboride is mainly used to prepare composite ceramic sodium silicate, etc. If you are looking for high-quality materials, please feel free to contact us and send an inquiry.
