Product Overview

Cobalt tetroxide belongs to transition metal oxides, which are in powder form and generally appear gray black or black in color. Its molecular weight is 240.8, density is 6.11cm2/g, and melting point is 895 ¡ãC At room temperature, cobalt trioxide material is insoluble in water. When the temperature reaches above 900 ¡ãC cobalt trioxide (Co3O4) decomposes into cobalt trioxide (Co2O3) and cobalt oxide (CoO), and the final products will stabilize into CoO. Meanwhile, cobalt trioxide is also a p-type semiconductor and antiferromagnetic material with a bandgap width of 1.5 eV. Co3O4 is a spinel type oxide with a lattice parameter of approximately 0.809nm. There are three methods for preparing cobalt trioxide based on the physical state of the required cobalt source: solid-phase method, gas-phase method, and liquid-phase method.

Pricey for quality but my dogs love them!
Size: Medium, Size: Medium
This toy is a bit on the pricey side for what it is, and no matter how many times I try to tie it, I just cannot get it to stay secured. I really like the idea behind it, but the overall quality feels just okay rather than amazing. The ball itself is very lightweight and almost feels more like a dense foam than traditional rubber, which initially threw me off. That said, it has actually been holding up well with regular use, which is a pleasant surprise. Most importantly, my puppies absolutely love these. The biggest win for me is that it comes as a two pack, which means I can play with both dogs at the same time without anyone feeling left out. At the end of the day, my girls are happy, and that makes me happy too.

Sturdy and soft like hiking on clouds
Size: Large, Color: Color Mix
I am in love with these socks! In fact I've reordered five more times and have told my hiking friends about them, and they've ordered them now, too. We all love them. This is an excellent price for a 70% Merino wool sock. They wick away moisture & keep your feet nice and dry and comfortable in your boots. They're very cushiony yet your feet do not overheat. I bought these for the gym and for hiking. I actually hike about a hundred miles a month so I can tell you these socks go through a lot with me! The ankle cut socks are perfect for both my trail runners and my actual low ankle boots. The arch support keeps the sock firm on my foot and does not allow the sock to bunch up down towards the toe. The Merino wool helps to control moisture and my feet do not stink after a 6-7 mile hike. And oh my gosh they are so soft! It's like walking on clouds. I've had no issues with holes in the socks and will definitely update later if I do. I highly recommend these socks and tell your friends about them too

Comfy & amazing!!!
Size: Medium, Color: Colorful, Size: Medium, Color: Colorful
Oh my goodness! I have never been obsessed with a pair of socks but, here we are. They are thick which I usually dislike but they don’t feel thick even with my chuck taylors on, I usually have either sweaty or cold feet they are neither in these. Love love love the colors so vibrant, haven’t washed any yet will update on how it wears. No toe fuzzies, color transfer to feet, they fit so well, barely a seam…dare I say these are my perfect socks! Wish the price was not so much, which honestly for what I’m getting isn’t that bad but I’m poor… GO GO WOOL!!! BAA

Large a tad small for 11 mens supercomfy and well made
Size: Large, Color: Color Mixed(quarter Socks)
These are quality socks, but for me the large are a bit small at size 11 shoesize. They are warm in any conditions, and warm days they can feel a bit stiffling, and I have probably sweatier than average feet, so without well ventilated shoes, my feet still get damp. They are so soft and cozy in cooler/cold weather. But again, it the heat, with some sweat, this makes them a bit "slippery" and my feet slide in my shoes on steep off-camber terrain. I would probably buy these again, except I have 6 pairs, and my wife buys me expensive branded socks I'd never purchase for myself.
