I understood only a very small amount of zirconia was used in brake pads, and even then mostly only in higher quality 'ceramic' pads for high performance cars.
"NAO brake formulations were designed to replace asbestos brake pads. NAOs employ the use of a matrix of organic and inorganic fillers, friction modifiers, abrasives, and binders. While not considered a fully ceramic material, it is common to have NAOs referred to as �ceramic� due to the practice of using materials like potassium titanate, ceramic fiber wool, silica, zirconia, alumina, silicon carbide, and others as fillers and abrasives.
Ceramic pads are quieter, produce little dust, have less rotor wear and offer superior braking performance. However, they are more expensive and are typically used only in premium vehicles or in extreme operating conditions."

It doesn't sound like there is much zirconia in the pads of your average Hyundai hatch ?
I'd be more worried about the ceramic tile manufacturers reacting to the the price volatility. But I'm sure the Zircon Conference didn't want to talk about the elephant in the room.
