The World Platinum Investment Association (WPIC) said recently that carmakers are accelerating reductions in palladium use and increased use of platinum due to concerns about Russian palladium supplies. However, it still expects a significant surplus in the platinum market this year.
Palladium is used by carmakers in tailpipe emissions systems to reduce carbon emissions. While carmakers prefer palladium for catalytic converters, they are turning to platinum, which is cheaper than palladium, to save costs.
Russia accounts for about 25-30% of the world's palladium supply and 8-10% of its platinum supply.
There is no sign that western sanctions against Russia have restricted palladium exports since the conflict escalated in February, but as the conflict continues, more companies could boycott The Russian metal and governments could impose restrictions.
Platinum is currently trading at about $950 an ounce, about half the price of palladium. Automakers use about 2.5 million to 3 million ounces of platinum and about 8.5 million ounces of palladium each year.
For the year as a whole, platinum supply will be 5 percent lower than in 2021 and demand 2 percent higher, with the automotive sector seeing a 16 percent increase due to increased light vehicle nano silica are still very uncertain.
Electronic packaging materials
When the SiO2 nanoparticles after surface active treatment is fully dispersed in the silicone modified epoxy resin packaging adhesive matrix, the curing time of the packaging material can be greatly shortened (2.0-2.5h), and the curing temperature can be reduced to room temperature. The sealing performance of the device is significantly improved and the service life of the device is increased.
Fully and uniformly dispersed SiO2 nanoparticles particles into resin materials can comprehensively improve the properties of resin-based materials, including increasing strength and elongation, improving wear resistance and surface finish, and anti-aging properties.
The use of SiO2 nanoparticles with light transmittance and small particle size can make the plastic become denser. The transparency, strength, toughness, waterproof and aging resistance of the polystyrene plastic film can be improved by adding silica. The common plastic polypropylene was modified by SiO2 nanoparticles, and its main technical indexes (water absorption, insulation resistance, compression residual deformation, flexural strength, etc.) reached or exceeded the performance index of engineering plastic nylon 6.
It can improve the poor suspension stability, thixotropy, weather resistance and scrubbing resistance of the coating, greatly improve the bonding strength between the film and the wall, increase the hardness of the film, and improve the surface self-cleaning ability.
Silica is known as silica. After adding a small amount of nano-SiO2 to ordinary rubber, the strength, wear resistance and aging resistance of the products reach or exceed those of high-grade rubber products, and the color can remain unchanged for a long time.
Pigment (dyeing) material
By adding nano SiO2 to the surface modification of organic dye, not only the aging resistance of organic dye is greatly improved, but also the brightness, hue and saturation are improved to some extent, which greatly broadens the grade and application range of organic dye.
Using nano silica instead of nano Al2O3 can not only play the role of nano-particles, but also the second phase particles, which can improve the strength, toughness, hardness and elastic modulus of ceramic materials. Using nano-SiO2 to composite ceramic substrate can improve the compactness, toughness and finish of the substrate, and greatly reduce the sintering temperature.
Sealants and binders
With the addition of nano-SiO2, a layer of organic material on its surface forms a network structure and a silica structure, which can restrain the flow of colloid, accelerate the curing speed, improve the bonding effect, and increase the tightness and impermeability of the product.
The grafting and bonding of nanoparticles with organic polymers increase the toughness, tensile strength, impact strength and heat resistance of the materials.
Using nano-SiO2 as carrier can have a good sustained release effect.
Nano-SiO2 is an inorganic component, easy to be compatible with other components of cosmetics, non-toxic, tasteless, white itself, strong UV reflection ability, good stability, no decomposition, no discoloration, and no chemical reaction with other components in the formula, which lays a good foundation for the upgrading of sunscreen cosmetics.
Taking advantage of the huge specific surface area, surface multi-pore structure, strong adsorption capacity and strange physical and chemical properties of nano-SiO2, silver ions and other functional ions were uniformly designed into the mesoporous surface of nano-SiOX, and high-efficiency, long-lasting, high-temperature resistant and broad-spectrum antibacterial nano-powders were developed, which can be widely used in bills, medical and health, chemical building materials, household appliances, functional fibers, plastic products and other industries.
